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
Two cursors layered on top of each other (the OS arrow / crosshair
icon plus the CAD crosshair drawn in `SelectionCanvas::draw`) looked
busy and made it harder to see what was pickable. `Interaction::None`
was the first try but `Stack::mouse_interaction` skips that value as
"no opinion" — the correct hide signal is `Interaction::Hidden`,
which iced_winit maps to a hidden cursor.
Over a Model-tile divider the OS now wins (resize arrow), and the CAD
crosshair is suppressed in `draw` via the same `tile_edge_under`
helper that mouse_interaction uses.
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.
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.

Dinamik giriş artık cursor yanında düzenlenebilir kutular gösteriyor.
TAB ile kutular arası geçilir, bir kutuya yazınca o kutu kilitlenir
(değer sabitlenir), diğerleri cursor'ı takip etmeye devam eder, Enter
ile çözülen nokta komuta point-pick olarak iletilir.
- DocumentTab.dyn_fields / dyn_active state; DynComponent + DynFieldEntry
- sync_dyn_fields komutun dyn_field() + base noktasına göre kutu kümesini
türetir: nokta+base → [d, açı], nokta+base yok → [X, Y], radius → [d],
açı → [açı]
- klavye yönlendirme: rakam/./-/+ aktif kutuya, TAB sonraki kutuya,
Enter try_dyn_commit, Backspace kilidi açar
- dyn_capturing iken command-line text alanı on_input'suz bırakılıyor
ki focus'u ve tuşları çalmasın; girişler global key aboneliğinden
geliyor (numpad dahil text alanı üzerinden yakalanıyor)
- çoklu-kutu overlay render: aktif kutu vurgulu, kilitli kutu farklı

Replaces the binary Wireframe/Solid toggle with a 7-mode dropdown
that maps onto acadrust's `ViewportRenderMode` enum: Wireframe 2D /
Wireframe 3D / Hidden Line / Flat Shaded / Gouraud Shaded / Flat
Shaded + Edges / Gouraud Shaded + Edges. Per-tab state lives on
`DocumentTab::render_mode`; the old `SetWireframe` message forwards
to `SetRenderMode` so the ribbon + WIREFRAME / SOLID command line
keep working.
`scene::render::render_mode_flags()` translates the mode into three
pipeline-facing booleans (`face3d_fill`, `mesh_fill`,
`show_3d_edges`); `mesh_fill` / `show_3d_edges` are stubs that the
upcoming phases will consume. `Primitive` carries the derived
`view_wireframe` plus the two new fields through to `prepare()`.
`Pipeline::upload_face3d` takes a `wireframe_only` flag that drops
3DFACE quad fills (built from `key_vertices`) while keeping the
`all_wires.fill_tris` channel — that channel carries text-LOD greek
rectangles and PolyfaceMesh face triangles which must stay visible
in wireframe mode. 3DFACE edges stay on regardless of mode.
Solid3D mesh wireframe rendering, Hidden Line z-prepass, and Flat /
Gouraud shader uniforms come in phases 1–4.

Replace the flat fixed-length axis arrows with a proper 3D tripod:
- Axis lengths are proportional (longest fills UCS_ICON_LEN, shorter
axes stay foreshortened) giving real depth perception as the camera
rotates
- Draw order computed from NDC Z so back axes render behind front ones
- X / Y / Z labels rendered beyond each arrowhead tip
- All axes drawn at full opacity with solid filled arrowheads

- Hide OS crosshair and drawn crosshair when cursor is over ViewCube area
- Enhanced hover glow in WGSL shader (blue tint + brightness boost)
- Fixed region_centroids() Y-axis sign for all FRONT/BACK-related regions
- Swapped corner geometry assignments (TPF↔TBK, BTF↔BBK) to match
intended FRONT/BACK semantics (sy=-1 = FRONT, sy=+1 = BACK)
- Corrected all snap_angles: yaw_pitch_to_quat(0,0) places eye at -Y
(FRONT view), so FRONT=0 and BACK=PI — cascaded through edges/corners

Viewport right-click now shows a proper widget-based context menu:
- When a command is active: Cancel / Enter
- Otherwise: Repeat last commands, Delete/Move/Copy (if selected),
Select All, Zoom Extents
CONSTRUCTIONLINE added as an alias for XLINE (XL).
Canvas-drawn placeholder removed; context menu closes on Escape,
click-outside, or when any action is taken.

- snap/mod.rs: Snapper gains otrack_enabled, tracking_points, dwell state;
update_otrack_dwell() acquires a snap point after DWELL_THRESHOLD=4
consecutive moves near the same position; otrack_snap() returns an
H/V alignment snap position; clear_tracking() resets state on command end
- overlay.rs: selection_overlay accepts ost_points + cursor_screen;
draws light-blue dashed H/V lines from acquired points + small cross marker
- statusbar.rs: OTRACK pill (F11) added next to DYN
- view.rs: projects tracking_points to screen, passes to selection_overlay
- update.rs: calls update_otrack_dwell + otrack_snap in ViewportMove;
overrides effective point with OST alignment when no normal snap is active
- ROADMAP.md: Object Snap Tracking marked ✅

- statusbar: DYN toggle pill with F12 tooltip (calls ToggleDynInput)
- app/mod.rs: dyn_input: bool field (default true), ToggleDynInput message
- view.rs: builds DYN label and pushes overlay into viewport_stack when
dyn_input=true and a command is active
- document.rs: last_cursor_screen: iced::Point — updated on every ViewportMove
- ROADMAP.md: Dynamic Input overlay marked ✅

Grid snap (F9):
• snap spacing now tracks the visible grid zoom level — computed via
compute_grid_step() (same adaptive pow-of-5 logic as draw_grid),
updated on every ViewportMove so zooming in/out keeps snap aligned
with the grid lines on screen
Polar tracking (F10):
• configurable angle increment stored in polar_increment_deg (default 45°)
• right-click the POLAR pill to cycle through 15 → 30 → 45 → 90°
• pill label shows current angle ("POLAR 45°")
• visual guide line: while drawing with polar on, a dashed cyan line is
drawn from last_point along the snapped direction across the viewport
• SetPolarAngle message + handler; all polar_constrain() calls use the
stored increment instead of the hardcoded 45°
ROADMAP updated: Grid snap and Polar tracking marked ✅.

Before layout completes the viewport bounds are 0×0, causing project_point3
to produce NaN/Inf coordinates which panicked in lyon_path assertions.
Added early-return when bounds < 10px, and finite checks on all projected
and derived coordinates before calling any canvas drawing functions.

Screen-space UCS icon drawn on the existing selection canvas overlay.
Axes are projected from world space so the icon rotates with the camera,
always showing the correct X/Y/Z orientation relative to the drawing plane.
Each axis has its canonical color (X=red, Y=green, Z=blue) with arrowheads.
Icon visibility controlled by show_ucs_icon flag (default on); toggled by
UCSICON ON/OFF command which also updates paper-space viewport entities.
