Two paper-space rendering fixes:
- The full-canvas sheet instance no longer draws model-block hatches/
wipeouts/images. Those belong inside the floating content viewports;
rendering them on the sheet let them bleed past the viewport borders
when model coords overlapped the paper area. The sheet now draws only
the paper block's own fills plus the synthetic white printable area.
- Pan/zoom/orbit inside a double-clicked floating viewport (MSPACE) now
re-culls and re-uploads the viewport's wire set. The per-viewport wire
cache key now hashes the viewport's own view (pan + zoom + orbit), and
the active-viewport pan/zoom/orbit handlers bump camera_generation so
the GPU re-uploads. Previously the stale frustum-culled subset stayed
on the GPU, so newly-revealed lines were invisible (hatches, uploaded
as the full set, still showed) until MSPACE was exited.

The overall "sheet" viewport now IS the paper view, so its own border
rectangle must not be drawn as an entity — filter it out of
paper_sheet_wires_arc (content viewport borders are kept).
Also update the doc comments that still referenced the removed
PaperCanvas widget / paper_canvas_wires to describe the GPU sheet path.

Paper space now renders entirely through the unified GPU shader, exactly
like model space — there is no separate 2-D canvas. The full-canvas
top-locked "sheet" viewport draws the layout's entities, hatches,
wipeouts and images; the desk is the container background and the white
printable area is a synthetic solid hatch.
- The white sheet fill uses draw_depth -2.0 (entity fills/wires are in
the signed (-1, 1) range) so it is always strictly behind every object,
with a negligible z offset (BIAS 0.001) — no far-plane clipping.
- Delete src/scene/paper_canvas.rs (the PaperCanvas widget) and its dead
helpers (paper_canvas_wires / paper_sheet_wires / paper_canvas_cache).
paper_canvas_hatches / _wipeouts remain — still used by paper hit-test.

Paper space now renders its sheet through the unified shader, the same
path as model space: a full-canvas "sheet" ViewportInstance draws the
layout's own entities + viewport borders + interim/preview wires, with a
camera locked to the top/plan orientation (paper is 2-D and never
orbits). Floating content viewports overlay it.
- PaperCanvas no longer draws entity wires (still paints the desk, sheet
and hatch/wipeout/image fills; full removal is the next step).
- Right-drag on the paper sheet no longer orbits the camera (it would
corrupt the frame and skew subsequent pans).
- Fix floating-viewport orbit oscillation: orbit_active_viewport wrote
view_direction.y negated while camera_for_viewport reads it un-negated,
so each drag step read back a Y-mirrored camera and flipped the model
between a rotation and its opposite every frame. Store eye directly,
matching snap_active_viewport_to_direction and the reader.

Persist the paper-space camera through the sheet viewport entity (which
round-trips natively in both DXF and DWG) instead of the
OpenCADStudio_Camera_* named-View side-channel:
- apply_sheet_viewport_camera reads the sheet viewport entity first; the
named View is only a backward-compat fallback for older files.
- sync_camera_to_document (paper) writes the camera only to the sheet
viewport entity. Model branch is unchanged.
- Add Scene::ensure_sheet_viewport: guarantee every paper layout has its
full-screen overall (id==1) viewport, creating one if a loaded file
lacks it; wired into layout enter and add_layout.
- Restore the owner-handle guard on the sheet-viewport finder so a
foreign layout's viewport can't be picked as the sheet viewport.

Single-click selection only tested wire-edge proximity, so clicking a
solid's face missed — only its thin projected edges were selectable.
Add mesh_click_hit: project each mesh triangle to screen and test the
cursor against it (front-most wins), wired as a fallback after the wire
and hatch hit-tests. Works for any meshed solid.

Rename the Home tab to "Draw" and add a Model tab beside it with two
groups:
- Model: BOX / CYLINDER / CONE / SPHERE / WEDGE / TORUS, placed with a
footprint + height. Each is built as a real ACIS Solid3D (acadrust
primitive builders) plus a truck B-rep, tessellated into the shaded
mesh pipeline, with edge wires for picking + wireframe.
- Design: UNION / SUBTRACT / INTERSECT via truck-shapeops.
A session-only Scene.model_solids cache holds each solid's truck B-rep
so the boolean tools can combine and chain them. Supersedes the old
command-line BOX/SPHERE/CYLINDER (insert::solid3d_cmds keeps EXTRUDE/
REVOLVE/SWEEP/LOFT).
Known limitations: booleans need solids created this session; curved
ACIS primitives render in-session but not after reload (the SAT
tessellator handles only planar caps); geometry assumes world_offset 0.

Type directly into the rendered MText preview: click to position the
caret, insert/delete, Enter for a new line, Space for a literal space,
and arrow keys to move. The caret blinks when idle.
Keep the trailing empty paragraph in the editor so the caret appears on a
fresh line immediately after Enter, before any typing. parse_mtext_paragraphs
split into a _ex variant; layout_mtext skips the blank-edge trim when
emitting glyph boxes.

The rendered MText preview is now an editable surface: it shows a text caret,
click to position it between glyphs, and type/Backspace/Delete/Enter to edit.
Left/Right arrows move the caret; drag-selection + toolbar formatting still
work and typing replaces a selection.
Keystrokes are routed by mapping visible-character offsets to byte spans in
the value (raw newlines count as paragraph breaks, matching the layout). While
the preview is open the command line releases its on_input so typed glyphs
reach the preview instead, and the caret starts at the end of the text so
typing works without a click first.

Restore complex-linetype embedded shapes: ltypeshp is converted from the old
CXF shape file to LFF (assets/fonts/ltypeshp.lff), with the bulge moved to the
LibreCAD preceding-segment convention. The LFF parser now keeps named shapes
(blocks whose label is a word, e.g. BOX/CIRC1/ZIG) in a separate map since
their codepoints collide, exposed via lff::shape(); complex_lt::emit_shape
draws them again at the pen position.
Missing glyphs now fall back through the chosen family -> unicode -> iso3098,
so Turkish letters (Ğ ğ Ş ş İ) render in any font (dotless ı is the lone gap
iso3098 lacks).

Replace the small QCAD CXF stroke-font set with the full LibreCAD LFF font
library (46 fonts) and a new LFF parser/engine in src/scene/lff.rs. The
parser reads the `[hex] char` glyph blocks, tessellates `,A<bulge>` arcs, and
resolves `C<hex>` glyph references. Per LibreCAD's RS_Polyline convention a
vertex's bulge curves the segment ending at that vertex — getting this wrong
turned round letters like O into sideways capsules.
Font name resolution mirrors LibreCAD: match by file stem, map common
AutoCAD/DXF SHX names (txt, isocp, complex, italic, gothic*, gost, …) to the
nearest LFF family, and fall back to `standard`. A missing glyph in the chosen
family falls back to the broad `unicode` font so accented/Cyrillic/Greek text
still renders. Cap height stays 9 units, so the text scale is unchanged.
All text consumers move from cxf:: to lff::; complex linetypes still render
embedded text but no longer draw embedded shapes (LibreCAD ships no shape
file). The CXF module and every *.cxf asset are removed, and the MText / text
style font pickers list the LFF families.

Single-click picking cleared the selection first (exclusive), so clicking a
second object dropped the first (issue #47). Plain clicks now add to the
selection and Shift+click removes the picked entity; empty-space click and
Esc still clear. Shift state is tracked from keyboard ModifiersChanged
events since mouse click messages carry no modifiers.

The viewport context-menu item dispatched a bare "ZOOM" string, which no
command branch handled, so it did nothing. Send "ZOOM EXTENTS" instead.
fit_all() also fed on the frustum-culled wire set, so it only framed the
entities already on screen — each invocation revealed a little more and the
view converged on the true extent only after several uses (issue #51). It
now builds an un-culled wire set at a fixed tessellation tolerance, so the
bounds are zoom-independent and the first call fits the whole drawing.

DRAWORDER now affects rendering immediately (bump geometry epoch so the
sort cache rebuilds) and front/back anchor to the block's full effective
sort range instead of only existing table entries, so bring-to-front
actually lands on top. The render fallback sorts table-absent entities by
their own handle.
Draw order now applies across entity types, not just within a type. A
per-entity draw-order rank (SortEntitiesTable override or own handle,
ranked per block) is encoded as a small signed clip-z bias in the wire,
hatch, image, and 3DFACE pipelines. The shared LessEqual depth buffer then
orders fills, lines, rasters and 2D solids against each other regardless of
pass order — without touching model coordinates. 3D meshes keep real
geometric depth; wipeouts stay always-on-top.
Adds a Draw Order submenu to the viewport context menu (Bring to Front,
Send to Back, Bring Above/Send Under Object). The above/under items run an
interactive reference-object pick, then reorder the captured selection.

Quick Select used to filter only on Object Type and Layer. The classic
QSELECT model — pick a type, pick one of its properties, compare with a
typed value via a logical operator — is much more general: a Line entity
can now be filtered on Start X, Length, Angle, Delta Y, …, and any
entity on the common Layer / Color / Linetype / Lineweight.
Panel layout: Object type → Property → Operator → Value → Append. The
Property dropdown is type-aware: it always lists the four common
properties; picking a specific Object type appends that type's
`geometry_properties` rows, sampled from the first entity of that type
in the active layout (so `Start X`, `Radius`, `Pattern Angle`, … only
appear when their entity type is selected). Changing the Object type
drops the Property when the new type no longer offers it.
Operators: `= Equals`, `!= Not equal`, `> Greater than`, `< Less than`,
`* Any value`. Eq/Neq do case-insensitive string compare against the
canonical property string (so "ByLayer" matches "bylayer"); Gt/Lt parse
both sides as `f64` and reject anything non-numeric; Any skips the
value test entirely. The Value text field is disabled when no Property
is picked or the operator is Any. Append behaves the same as before.
The new value reader is hand-rolled for the four common properties
(layer name, color formatted as `ByLayer`/`ByBlock`/`<aci>`/`r,g,b`,
linetype name, lineweight formatted as `0.30mm`) and falls back through
`geometry_properties()` for type-specific fields — extracting the
property's value out of the `PropValue` variant so EditText / Choice /
ColorChoice all canonicalise the same way the panel will display them.

Two ways to extend the current selection by entity type + layer:
* `Select Similar` (right-click → Select Similar, or `SELECTSIMILAR` /
`SELSIM`): for every (type, layer) pair in the current selection, add
every entity in the active layout that matches the pair. The seed
selection stays selected; matches already selected are not
double-counted.
* `Quick Select` (right-click → Quick Select…, or `QSELECT` / `QS`):
opens a centred floating panel with Object-type and Layer pick_lists
(populated only with values that actually exist in the active layout)
and an "Append to current selection" checkbox. `(Any)` in either slot
skips that filter. Apply replaces the selection (or extends it with
Append on) and reports the match count on the command line. Cancel,
Esc, and outside-click all dismiss without applying. When opened with
a selection present, the panel pre-fills both filters from the first
selected entity so QSelect doubles as an editable Select Similar.
Scoped to entities owned by the active layout's block-record so a paper
layout's QSELECT never reaches into model-space entities (and vice
versa). Entity-type names live in a single `entity_type_name` helper in
`entities::traits` to keep the UI strings and the filter keys aligned.

The previous single-widget refactor left the column at
`Length::Shrink` and the buttons at `Length::Fill`, which iced
resolves to a zero-width column — the popup degenerated into a
1-pixel vertical line. Set the column to a fixed pixel width
derived from the longest item's label (and restore `width(Fill)`
on the buttons) so the selection highlight covers the full row
instead of just the text glyphs.
Also silences a `dead_code` warning on `GripMenuAction` variants
that the Phase 2 / 3 wiring will consume next.
Phase 2 of the grip overhaul: when the cursor dwells on a selected
entity's grip the overlay opens a popup menu with entity-specific
options (Stretch / Add Vertex / Remove Vertex / Convert to
Arc-Line / …). Picking an item dispatches `apply_grip_menu`; the
default `Stretch` entry is a no-op that lets the user click the
grip to start the normal drag.
- `GripMenuItem` + `GripMenuAction` (full vocabulary covering
stretch, add/remove vertex, convert to arc/line, reverse arrows,
text-position variants, hatch parameters, tangent direction).
- `Grippable` trait gains `grip_menu` + `apply_grip_menu` with
trait-default `Stretch`-only impls so every existing entity gets
the popup for free.
- `EntityTypeOps` dispatches both methods across the same entity
list as the existing grip / property machinery.
- `OpenCADStudio` carries `grip_hover` (dwell tracker) +
`grip_popup` (open menu). `update_grip_hover` runs from
`ViewportMove`: hit-tests grips, refreshes the dwell timer, and
opens the popup after 600 ms. Cursor drift past 80 px or a grip
click dismisses it.
- `view.rs` paints the popup as an absolute-positioned column of
buttons at the grip's screen anchor; each button publishes
`Message::GripMenuPick(idx)`.
- `LwPolyline` overrides `Grippable` manually (skips the standard
macro) so its vertex grip exposes Add/Remove Vertex and its
segment-midpoint grip exposes Add Vertex + Convert to Arc/Line.
`apply_grip_menu` performs the edits: vertex insertion at the
chord midpoint inheriting the previous bulge, vertex removal,
and bulge toggle for the arc/line conversion.
Phase 1 of bringing the grip vocabulary in line with the standard
CAD convention: drop the per-position-type shape encoding (Diamond
for translate, Circle for parameter) and use a plain square for
every endpoint / vertex / centre grip. The behavioural midpoint vs
vertex distinction stays — it lives on `GripDef::is_midpoint` and
drives `Translate` vs `Absolute` in the grip-edit dispatcher — only
the marker shape collapses.
- `GripShape` keeps `Square`, `Rectangle`, `Triangle`. Diamond /
Circle are gone.
- `GripDef` gains `dir: Option<[f32; 2]>` — a world-XY direction
vector consumed by `Rectangle` to orient the box along its
segment.
- `entities::common` exposes `square_grip`, `center_grip` (same
square marker, flagged as translate), `rectangle_grip(id, world,
dir)` for oriented mid-segment handles, and a kept-for-Phase-2
`triangle_grip`.
- `overlay::GripMarker` / `grips_to_screen[_paper]` thread `dir`
through to the canvas painter; the Rectangle path rotates the
box around the grip centre using the world-XY direction (flipping
the sin for screen-Y).
Every existing `diamond_grip(id, w)` call becomes `center_grip(id,
w)` — the visual change is square-replacing-diamond at line
midpoints / arc midpoints / circle centres / ellipse centres /
viewport / hatch loop centroids / dimension grips / image corners /
multileader / ray / underlay / ole2frame / solid3d.
`LwPolyline` grows a stretch handle on every segment (straight or
arc), drawn as the new oriented rectangle. The grip-edit path
translates both segment endpoints for straight segments and
adjusts the arc bulge from the new midpoint for arc segments.
Existing entity grip definitions already followed the conventional
CAD layout: square at vertices / endpoints, diamond at curve
centres / midpoints, triangle for directional control. Round out
the supported shape vocabulary with the two missing standards so
future entities (polyline straight-segment stretch grips, dimension
parameter grips, …) can pick the right marker without inventing
ad-hoc visuals:
- `GripShape::Rectangle` — direction-aware mid-segment stretch
handle (wider-than-tall box).
- `GripShape::Circle` — parametric control (radius / dimension
value).
New `rectangle_grip` / `circle_grip` helpers in `entities::common`
mirror the existing `square_grip` / `diamond_grip` / `triangle_grip`
constructors. `SelectionCanvas::draw` renders the two new variants;
the previously-used Square / Diamond / Triangle paths are
unchanged. Both new variants carry `#[allow(dead_code)]` until an
entity adopts them.
Two bugs from #34:
1. Hovering a circle showed the Center snap as a diamond instead of
the conventional circle outline.
2. Hovering a circle also showed Midpoint hits (triangle marker)
even though a closed curve has no midpoint.
(2) came from a "tessellated curve" fallback in the Midpoint snap
path that produced a midpoint for every chord of the polyline
approximation. Drop that fallback — only entities with explicit
`key_vertices` (Line, LwPolyline) contribute per-segment midpoints
now. Curves that DO have a single well-defined midpoint (arcs, and
later splines) declare it explicitly via a new
`SnapHint::Midpoint`; `arc.rs` emits one at the arc-length centre.
(1) — and the broader "everything past Endpoint / Midpoint / Grid
was a diamond" inconsistency — fixed by giving every `SnapType` a
distinct marker in `SelectionCanvas::draw`:
- Center: hollow circle
- Node: circle with inscribed X
- Quadrant: diamond (unchanged)
- Intersection: X
- Apparent Intersection: X inside a square
- Insertion: two overlapping rectangles (tag glyph)
- Perpendicular: right-angle hook
- Tangent: circle with a bar across the top
- Nearest: hourglass / bowtie
- Extension: three dots
- Parallel: two parallel diagonal bars
- Endpoint / Midpoint / Grid: unchanged
Closes#34
`tessellate_sub_local` and `build_nested_ref` baked `adapt_to_bg`
results into the cached `BlockCache`, keyed against whatever bg was
live at cache-build time. Paper-space content viewports render
through model content with `paper_bg_color`, but if the cache had
been built earlier against `bg_color` (or vice versa, after the
recent layout-switch dance) the cached sub-wire colours were
already adapted to the wrong bg and `expand_insert` emitted them
verbatim.
Store the raw `render_style_for` result on `LocalWire.color` /
`NestedRef.ins_color` and run `adapt_to_bg` in `Batches::finalize`
with the per-render `bg_color` that `expand_insert` already
threads through. The same cached defn can now serve renders
against any background — paper viewports get `paper_bg`-adapted
sub-entities, model renders get `bg_color`-adapted sub-entities,
no rebuild required.
Double-adaptation (ByBlock sub inheriting an already-adapted
`ctx.ins_color` from `tessellate_entity`) is idempotent: a pure
white that adapted to black on a white bg stays black through a
second adapt against the same bg.
`adapt_to_bg` (pure black → white on dark bg, pure white → black on
light bg) was only running through `render_style`, which the wire and
per-frame hatch paths already use. The mesh population paths and the
file-load hatch path went straight through `aci_to_rgba`, so:
- ACIS solids / regions / bodies appeared in their raw ACI colour
even when that colour was pure white on a white paper bg.
- The initial hatch upload used the unadapted colour for the first
frame after load (`synced_hatch_models` then re-ran adaptation per
frame, so the issue cleared after one redraw — but visible).
Now every mesh / hatch creation site funnels through
`render_style_for` + `adapt_to_bg`:
- `build_derived_caches` (load): uses the default model bg as the
adaptation target.
- `populate_meshes_from_document`: uses `self.render_style` so the
per-frame paper / model bg selection applies.
- New `Scene::recolor_meshes` rewrites every cached mesh's colour
field through `render_style`; called from `BACKGROUND` (after the
user changes bg) and `set_current_layout` (Model ↔ paper bg
switch) so ACIS mesh colour tracks the live bg without re-
tessellating ACIS geometry.
Wipeout fills stay bg-coloured by design (that's their job). Raster
images skip adaptation — pixel data is not entity colour.
The previous commit let model-block hatches into the shared
`hatch_models_arc` so paper-layout content viewports could pick them
up through their GPU pipeline. PaperCanvas was reading the same arc
and projecting every entry through the paper camera, so model hatches
got a second copy on the paper sheet — at huge / off-position
coordinates because their `world_origin` is in offset-subtracted
local space, not paper millimetres.
Split the canvas-side accessors:
- `paper_canvas_hatches` now iterates `self.hatches` directly (the
source map is keyed by entity handle) and keeps only entries whose
owner is the active paper-layout block. The flattened arc only
carries pattern names, so handle-based filtering had to move here.
- `paper_canvas_wipeouts` iterates entities likewise; paper-block
wipeouts get `[0;3]` `world_offset` so the boundary is in paper
millimetres.
GPU paths still call `hatch_models_arc` / `wipeout_models_arc` which
return everything — the per-viewport scissor / camera projection
silently culls the wrong-block hatches there.
Paper-space content viewports rendered the model's wires + meshes but
no hatches. `synced_hatch_models` only kept entries owned by the active
layout's block, so flipping to a paper layout dropped every hatch
created in model space from the arc that `viewport_data_for` uploads
to the per-vp GPU pipeline.
`populate_hatches_from_document` already bakes the right per-block
world_offset into each `world_origin` (model → `self.world_offset`,
paper → 0), so adding both buckets back is safe: projecting a paper-
block hatch through a model viewport's camera lands it outside the
frustum and the per-vp scissor / LOD culls it (and vice versa). No
double-rendering.
`wipeout_models` had the same shape of bug — its `world_offset` was
picked from the active layout instead of the wipeout's owner. Now it
chooses per-entity, so model wipeouts also show up in paper viewports.
Two world_offset bugs in viewport rendering.
(1) Solid3D / Region / Body meshes were tessellated straight out of
the ACIS SAT data in WCS, while the wire / hatch / face3d pipelines
all run in `(WCS - world_offset)` local space. At UTM scale the
result was triangles drifting millions of units off-camera every
frame. `offset_mesh_lod_set` post-processes the freshly built
`MeshLodSet`, subtracting `world_offset` from every vertex and
recomputing `world_aabb` so the LOD / cull math agrees with the
shared camera space. Applied at the three `tessellate_volume`
call sites — load, `add_entity`, and `populate_meshes_from_document`.
(2) Paper-space content viewports rendered blank on UTM drawings.
The DWG / DXF saved `view_target = (0, 0, 0)` while the model sat
around `world_offset`; the CPU projection in `viewport_content_wires`
already had a "saved view doesn't overlap content cluster →
auto-fit to (world_offset ± local_extent_max)" fallback, but the
GPU path read `vp.view_target` literally and culled every entity
against the empty WCS rect. `camera_for_viewport` now applies the
same overlap test + auto-fit, and `model_wires_for_viewport`
derives its frustum AABB / wpp from the resulting camera so both
the camera and the cull agree on which area to show.
Folding `view_center` directly into `effective_target_wcs` matches
the CPU path's `display_center_x = view_target + view_center`,
removing the prior `+ view_right * view_center.x` shift that would
double-count once auto-fit had overwritten the target.
`model_wires_for_viewport` previously passed `view_aabb: None` and
`wpp: None` to `tessellate_entity` — the assumption that paper-space
viewports were too small for culling to matter falls over the moment
the document carries 100k+ entities. Each frame re-tessellated the
full model through every floating viewport.
`wires_for_block_culled` grows two optional parameters
(`frozen_layers`, `anno_scale_override`) and now flips its
`world_offset` / `bg` / `anno` selection on `is_model_block` rather
than `current_layout`, so a paper-layout caller asking for the model
block still gets WCS-subtracted coordinates and the right annotation
scale.
`model_wires_for_viewport`:
- derives the viewport's frustum AABB from its (paper-zoom-invariant)
camera + entity aspect — 25 % margin to match `view_world_aabb`,
- derives `wpp` from the on-paper pixel height the viewport currently
occupies, so LOD stubs and zoom-adaptive curve sampling track the
paper-zoom state,
- delegates everything else to `wires_for_block_culled` so block /
layer / frozen-layer / curve-tolerance handling stays in one place.
`model_wires_for_viewport_arc` keys on `(geometry_epoch,
round(screen_height_px))` — sub-pixel jitter still hits the cache,
real paper-zoom steps invalidate. Hit-test / CPU-projection callers
pass `screen_height_px = 0.0` to get the no-LOD (full-fidelity) wire
list in their own cache slot.
Tiled Model panes were all reading from the shared `entity_wires_arc`,
whose tessellation runs `view_world_aabb` / `world_per_pixel` against
the live `Scene::camera`. Zooming the active tile re-built that arc
with the active camera's LOD / frustum cull, then every other tile
rendered from the same arc — content in the inactive panes flickered
between full and LOD-stub tessellations as you zoomed.
- `wires_for_block` now delegates to `wires_for_block_culled`, which
takes `view_aabb` + `wpp` explicitly. The original caller passes
the live-camera values; tile rendering passes its own.
- New `model_tile_wires_arc` builds a per-tile view AABB + wpp from
the tile's camera + pixel rect and caches the result. Cache is
keyed by tile index; the value holds `(geometry_epoch,
camera_state_hash)`, so a stale hit (camera moved, doc changed)
still misses and rebuilds.
- `ViewportInstance` gains `tile_idx` so `viewport_data_for` can route
Model tiles into the per-tile cache without disturbing the paper-
layout content-viewport path (it still uses `model_wires_for_viewport_arc`).
Tiled Model layouts now show the inner edges between panes as 2-px
dividers that act as resize grips: cursor on a divider → resize cue,
press + drag moves the edge (with every tile sharing that edge
updating together), release runs a collapse pass that absorbs any
tile that fell below the viewcube-comfort minimum into the neighbour
with the longest shared contact edge — drag a divider all the way
across to remove a pane.
- Scene grows `model_tile_edges`, `hit_model_tile_edge`,
`move_model_tile_edge`, `collapse_small_model_tiles`. Edges are
derived from the existing `model_tiles` rects (no extra storage).
- App carries a `tile_drag` Option; `ViewportLeftPress` starts it
ahead of tile activation / picking, `ViewportMove` drives the
edge, `ViewportLeftRelease` collapses + clears.
- `SelectionCanvas` draws the dividers and switches the cursor to
`Resizing{Horizontally, Vertically}` over them.
`model_wires_for_viewport` was tessellating with `self.bg_color` (the
model bg), so model content rendered inside a paper-layout viewport
adapted to a dark bg even though the transparent shader now reveals
the PaperCanvas sheet behind it — white wires stayed white on a light
sheet. Pass the paper bg in a paper layout.
Wire cache also needed an explicit invalidation when the bg or the
active layout changes; otherwise the cached, already-adapted wires
were returned against the new bg unchanged.
- BACKGROUND command bumps `geometry_epoch` after both branches
- new `Scene::set_current_layout` setter bumps on actual change; layout
switch + history restore use it
The previous off-canvas fix sized each per-viewport MSAA / depth /
resolve texture to the full viewport rect, then UV-cropped the blit.
With deep paper-space zoom that rect can grow past wgpu's 8192-pixel
texture limit and the program panics in `Device::create_texture`
("Dimension Y value 9493 exceeds the limit of 8192").
`viewport_data_for` now clips the screen rect to the canvas before
returning the `ViewportData`, so the per-viewport textures are bounded
by the surface (≤ canvas size, always within the GPU limit). The
camera frustum is still built at the *full* vp aspect (so the world it
projects matches the viewport entity), and a new `crop_view_proj`
post-multiplies the standard view_proj by a clip-space transform that
remaps the visible sub-rect to NDC `[-1, 1]^2` — the off-center ortho
that lets the visible-sized MSAA carry the correct portion of the
view. `viewport_size` is set to the visible size for the wire shader's
screen-space line extrusion; `world_per_pixel` is crop-invariant (the
`vs` factor cancels) so the value `Uniforms::new` computes from the
full bounds remains correct.
Viewports whose screen rect doesn't intersect the canvas at all return
`None` and are filtered out before any inner pipeline is allocated.

Refactor the per-viewport blit so a content viewport whose screen rect
extends off the canvas composites the correct slice of its MSAA target
to the visible portion of the surface, instead of being slammed against
the canvas corner by an `(f32 as u32)` saturation on the negative
offset.
- blit.wgsl + Pipeline gain a small uniform buffer (`uv_offset` /
`uv_scale`). `Primitive::prepare` computes the per-viewport crop from
`screen_rect`'s on-canvas fraction and writes it via the new
`upload_blit_uv` helper while it still has the `Queue`.
- `Pipeline::render` now takes `vp_size` (full vp — MSAA / camera size)
and `surface_dest` (visible intersection — blit destination) and
reads the crop from the uniform; passes that don't have a non-empty
surface intersection are skipped.
- `Primitive::render` clips the full vp rect against the surface clip
in `i32` and skips empty intersections. The earlier "skip GPU for
inactive off-canvas viewports" workaround in `active_viewports` is
no longer needed.
- ViewCube draws only when its hosting vp is fully on-canvas (its own
pipeline writes directly to the surface and would distort under a
clamped `set_viewport`).
With the GPU path correct for every vp position, drop
`viewport_content_wires` from `paper_canvas_wires` — the inactive
viewport CPU projection was only there to mask the blit bug and was
duplicating the unified shader's output. The hit-test / snap path
(`entity_wires_arc`, `wires_for_block`) still calls
`viewport_content_wires` directly, so picking through inactive
viewports keeps working.

Zooming the paper view in PSPACE grows each floating viewport's screen
rectangle until its edges run past the canvas. The per-viewport blit
computes its surface offset via `(screen_rect.x * cw) as u32`, which
saturates negative values to 0 — so a viewport hanging off the left
edge was being painted at the canvas top-left instead of its actual
position, producing a drifting ghost copy on top of the CPU projection
that PaperCanvas was already drawing correctly clipped.
`active_viewports` for paper now skips the GPU pass for any inactive
content viewport whose screen rect would extend beyond the canvas. The
CPU projection already handles those, so only one (correct) copy is
visible. The active viewport keeps the GPU path so its per-viewport
render mode (Hidden Line, Gouraud, …) still applies.

Geometry passes draw with standard `SrcAlpha / 1-SrcAlpha` into a
transparent MSAA target, so AA-edge fragments sit as `(rgb * a, a)` in
the resolve texture. The previous straight-alpha blit then multiplied
those by `a` a second time, darkening thin lines and curves over the
transparent background. `PREMULTIPLIED_ALPHA_BLENDING` matches what is
actually in the resolve texture and renders edges at full intensity
while still leaving fully-transparent pixels untouched on the surface.

A multi-pane Model view (split / VPORTS 2H|2V|4) used to collapse back
to a single tile after save→reopen — only the *Active VPort entry was
written, the rest of model_tiles was discarded.
Each ModelTile now round-trips through a dedicated `*OCS_Tile_<i>` entry
in the VPort table:
- save_model_tiles_to_vports stashes the live camera into the active
tile, removes any previous tile entries, and writes one VPort per
tile (rect via lower_left/upper_right, camera via
view_target/direction/height); the active tile is mirrored to
`*Active` so apps that only read that entry still get a sensible
view.
- restore_model_tiles_from_vports rebuilds the tile list on file open
and selects the active tile by matching the entry whose view_target
equals `*Active`'s, falling back to index 0.
Single-tile configurations and files from other apps skip the tile
entries entirely — restore returns false and the existing *Active /
View-table path runs, so behaviour for non-tiled files is unchanged.

Collapse the paper-space rendering path into the same shader widget the
model layout uses. The PaperCanvas widget draws the paper sheet, paper
entities and viewport borders underneath; the unified shader paints all
content viewports on top, scissored to each viewport's rect.
- Drop PaperViewportPane / PaperViewportPipeline newtype /
PaperViewportPrimitive, ViewportPaneMode::Paper, ViewportPane::paper,
build_primitive and build_viewport_primitive. Scene exposes only
build_viewports.
- view.rs: the paper branch stacks PaperCanvas + the unified shader
instead of the old paper_canvas_view function. The active paper
viewport's blue border, render-mode picker and ViewCube hit-area are
layered in the same viewport_stack as the model layout.
- Transparent shader clear (alpha=0) + alpha-blended blit pipeline so
the underlying widget (container bg in model, PaperCanvas sheet in
paper) shows through everywhere the shader has not painted geometry —
including inside content viewport rectangles.

Route every per-frame interaction through the active model tile's screen
rectangle so a tiled VPORTS layout behaves like independent panes while
still sharing one shader widget:
- pick / draw / snap / box+lasso: cursor mapped to tile-local space; the
hover-activates-tile rule on ViewportMove keeps the active tile under
the cursor, so the picked camera matches what the user sees.
- pan: switched to Camera::pan_screen(dx, dy, viewport_height) so the
world-per-pixel rate matches the active tile's height instead of the
full canvas.
- grid: clipped via Frame::with_clip to the active tile rect; world→screen
adds the tile origin so the lines align with the panel.
- UCS icon: origin offset by the tile rect so the gizmo sits in the
active tile's bottom-left corner.
- render-mode picker (+ split buttons) and ViewCube hit-area: positioned
via active_model_tile_bounds with leading Spaces, mirroring the
floating-viewport pattern.
- ViewCube hover: driven by the CursorMoved/ViewportMove handlers into a
new Scene::viewcube_hover cell, so the highlight survives the cube
hit-area overlay masking events from shader::Program::update.

Model space'de VPORTS artık iki aşamalı: bare VPORTS bir yapılandırma
istiyor (SIngle/2H/2V/4), sonraki komut-satırı girdisi düzeni kuruyor
(boş giriş = SINGLE). set_model_tile_layout normalized rect listesiyle
tiled düzeni değiştiriyor:
- SINGLE: tek tam-ekran
- 2H: üst/alt
- 2V: sol/sağ
- 4: 2x2
awaiting_vports app flag'i prompt sonrası girdiyi yakalıyor. Paper-space
VPORTS davranışı değişmedi.

Model layout artık tiled viewport destekliyor. Scene.model_tiles
normalized ekran rect'i + kamera tutan tile listesi; active_viewports
model layout'ta her tile için bir ViewportInstance üretiyor (aktif tile
canlı scene.camera'yı, inaktif tile'lar saklı snapshot'ı kullanıyor).
Render-mode picker'ın yanına iki buton eklendi: ▤ aktif tile'ı yatay
(üst/alt), ▥ dikey (sol/sağ) ikiye böler. split_active_model_tile
bölmeyi yapıyor; her iki yarı aktif kameranın kopyasını alıyor.
set_active_model_tile_at (cursor → aktif tile, kamera swap) ve
reset_model_tiles eklendi ama henüz bağlanmadı — aktif tile cursor
seçimi + pick yönlendirme sonraki adımda.

build_viewports, active_viewports'un ViewportInstance listesinden
viewport başına ViewportData üretiyor (model: tüm model wire'ları;
paper viewport: layer-freeze'li alt küme). Model space artık
ViewportPane::model -> build_viewports üzerinden birleşik çoklu-viewport
yolundan render ediliyor — şimdilik tek tam-ekran viewport, davranış
birebir aynı.
Paper space hâlâ eski yolda (PaperCanvas + PaperViewportPane); sonraki
adımda birleşik yola taşınacak.

Birleşik viewport mimarisinin yapısal temeli. Primitive artık tek kamera/
geometri yerine viewport başına bir ViewportData listesi taşıyor; yeni
MultiPipeline her viewport için bir iç Pipeline instance tutuyor.
prepare/render viewport listesi üzerinde dönüp her iç-pipeline'ı kendi
(normalized) ekran rect'ine çiziyor.
Mevcut Pipeline kodu (upload/LOD/render/blit) HİÇ değişmedi — sadece
viewport başına bir kez çalışıyor. build_primitive ve
build_viewport_primitive tek-elemanlı liste (FULL_VIEWPORT_RECT)
ürettiği için render davranışı tek-viewport ile birebir aynı; çoklu
viewport sonraki adımda (view.rs tek widget + active_viewports) aktive
edilecek.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
Birleşik viewport mimarisinin ilk parçası: tek render geçişinde
çizilecek viewport'ları tanımlayan ViewportInstance (handle, ekran
rect, kamera, render mode, aktif) ve bunları üreten active_viewports.
Model layout tek tam-ekran instance, paper layout her content viewport
entity'si için bir instance döndürüyor. Henüz render'a bağlı değil
(additive); mevcut davranış değişmedi.

Paper-space'de bir viewport'a çift tıklanıp aktif hale gelince, model
space'deki gibi sol üst köşede render-mode dropdown'ı ve sağ üst köşede
ViewCube gösteriliyor.
- render_mode_picker helper'a çıkarıldı; model space ve aktif paper
viewport ortak kullanıyor (kod tekrarı yok)
- SetRenderMode artık viewport-aware: aktif viewport varsa o viewport
entity'sinin render_mode'unu, yoksa model-layout tab stilini günceller
(Scene::active_viewport_render_mode getter/setter)
- build_viewport_primitive'e show_viewcube parametresi; aktif viewport
primitive'i ViewCube gizmo'sunu çiziyor
- PaperViewportPane shader::Program artık Message'a özelleşti ve sol
tık ViewCube hit-test'ini bounds-relative yapıp ViewCubeSnap üretiyor
Bilinen sorun: picker/viewcube doğru konumda görünüyor ancak tıklamalar
üstteki viewport_mouse mouse_area katmanına gidiyor; katman sırası bir
sonraki adımda düzeltilecek.

Koordinat girişi artık göreli/mutlak ayrımını destekliyor:
- `@x,y[,z]` → son girilen noktaya göreli (UCS eksenlerinde döndürülür)
- `#x,y[,z]` → her zaman mutlak (DYN durumundan bağımsız)
- ön ek yok → DYN açıksa göreli, kapalıysa mutlak
İlk noktada referans olmadığından göreli giriş mutlağa düşer. Çözülen
WCS noktası last_point olarak saklanıyor, böylece ardışık göreli
girişler zincirleniyor.
parse_coord artık (Vec3, CoordKind) döndürüyor; relative offset için
ucs_rotate_vec eklendi (origin translation olmadan UCS rotasyonu).
UCS ORIGIN komutu prefix'i yok sayıp mutlak kalıyor.
Ayrıca ViewCube snap refactor'undan kalan kullanılmayan kod temizlendi:
angle_close, active_viewport_yaw_pitch, CubeRegion::snap_angles.
Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
ViewCube tıklaması artık sabit (yaw, pitch) tablosu yerine bir yön
vektörüne (eye direction) snap ediyor. Up vektörü şöyle seçiliyor:
1. Mevcut up alın.
2. ±X / ±Y / ±Z arasından (yeni gaze ile (anti-)paralel olmayanlar)
mevcut up'a en yüksek dot-product veren cardinal axis'i seç.
3. Bu axis'i yeni gaze yönüne dik plane'e projekte et ve up olarak
kullan.
Sonuç:
- Küçük tilt'ler ilgili canonical axis'e snap olarak temizleniyor.
- TOP yukarıda iken TOP-LEFT edge tıklayınca TOP yukarıda kalıyor;
cube edge'e dönüyor ama kullanıcının "yukarı" hissi korunuyor.
- Upside-down orbit edilmişse -Z up olarak seçilir, snap baş aşağı
yapılandırmayı bozmuyor.
CubeRegion::snap_angles ve Camera::snap_to_angles yerini
snap_direction / snap_to_direction aldı.
snap_active_viewport_to_direction viewport'un view_direction'ını
günceller, twist_angle'a dokunmaz.

Yakındayken tessellate edilen 3D entity'ler (Face3D, Solid3D, Mesh,
PolyfaceMesh, PolygonMesh, Body, Region) <5 px eşiğine düştüğünde,
eski tek-çizgili stub'ın z=0 düzlemine indirilmesi yüzünden farklı
bir konumda görünüyordu. Yeni lod_stub_wire_3d entity'nin 3D AABB
kübünü (8 köşe, 12 kenar) çiziyor:
- XY'de entity_aabb local frame'i (world_offset shift edilmiş)
- Z aralığı bbox.min/max.z, world_offset[2] subtract edilmiş
2D entity stub'ı (lod_stub_wire) text fallback'leri ve diğer 2D
geometriler için z=0'da kalıyor.

PolyfaceMesh / PolygonMesh için outline edges WireModel.points üzerinden
gpu_wires'a giriyor; bu nedenle FlatShaded / GouraudShaded modlarında
shaded yüzeyin üstünde görünmeye devam ediyordu. WireGpu artık kaynak
WireModel'da fill_tris doluysa 'is_3d_mesh_edge' bayrağını set ediyor;
wire pass'i show_3d_edges=false iken bu instance'ları atlıyor.
*WithEdges, Wireframe ve HiddenLine modları show_3d_edges=true ile
geliyor — mesh kenarları orada görünür kalır.
