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.

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.

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.

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.

NAVVCUBE: propagate show_viewcube flag through ViewportPane and the wgpu
Primitive so the ViewCube pipeline skips upload/render when hidden.
UCSICON: bare command (no subcommand) now toggles current state instead
of printing usage info.

- paper_limits() falls back to A4 landscape (297×210mm) even when no
Layout object exists in the document
- paper_bg_color default changed to white [1,1,1,1] (paper surface color)
- PaperCanvas::draw() fills canvas with dark desk color first, then draws
the paper area rectangle in paper_bg_color so the sheet is clearly
visible against the desk background
- view.rs container background uses the fixed desk color instead of
paper_bg_color so it no longer conflicts with the paper-surface color
- BACKGROUND RESET for paper space now resets to white instead of dark gray
- Removed unused PaperSheet variant, paper_sheet() constructor,
build_paper_sheet_primitive() and associated match arms (dead code
after 2D canvas replacement)

When a paper-space viewport is activated (double-click / MSPACE command),
it is now rendered through its own dedicated PaperViewportPipeline rather
than the CPU-projection approach used for inactive viewports.
Architecture:
- PaperSheet widget (full-canvas): renders paper entities + CPU-projected
content of all viewports *except* the active one.
- PaperViewportPane widget (Fixed w×h, positioned at viewport screen rect):
renders the active viewport with a true 3D camera derived from the
viewport's view_direction/view_target/view_height.
PaperViewportPipeline is a newtype of Pipeline. Having a distinct type
gives it its own Iced storage entry (keyed by TypeId), preventing the
shared prepare() overwrite that broke the earlier per-viewport approach.
Changes:
- render.rs: PaperViewportPipeline, PaperViewportPrimitive newtypes;
build_active_viewport_primitive(); build_paper_sheet_primitive() now
excludes active_viewport from CPU projection.
- viewport_pane.rs: PaperViewportPane<'a> with shader::Program impl.
- mod.rs: viewport_content_wires() gains exclude_vp parameter;
viewport_screen_rect() is no longer dead code.
- view.rs: paper_canvas_view() overlays PaperViewportPane when MSPACE
is active.

Iced 0.14 batches all shader prepare() calls before any render() calls.
Multiple ViewportPane widgets sharing the same Pipeline type overwrite
each other's GPU buffers, causing the PaperSheet layer (full-canvas) to
render the last viewport's model content — appearing full-screen.
Fix: paper_canvas_view() now renders a single full-canvas PaperSheet
widget. build_paper_sheet_primitive() is updated to include model-space
content projected through each viewport's view matrix (via
viewport_content_wires()), restoring the original working behaviour.
ViewportPane::Paper mode and viewport_screen_rect() are kept with
#[allow(dead_code)] — a per-viewport wgpu sub-renderer that accumulates
data across frames could revive them in the future.

- Remove Scene: shader::Program<Msg> impl; all GPU rendering now goes
through ViewportPane which supports three modes:
Model — full model-space view (unchanged behaviour)
PaperSheet — paper-space entities only, using the paper camera
Paper — model content through a specific viewport's own camera
- Add Scene helper methods (render.rs):
build_primitive / build_paper_sheet_primitive / build_viewport_primitive
update_viewcube_state / viewcube_mouse_interaction
- Add Scene helpers (mod.rs):
paper_sheet_wires() — paper entities without viewport projection
camera_for_viewport() — derive Camera from Viewport entity data
model_wires_for_viewport() — model wires filtered by per-viewport frozen layers
viewport_screen_rect() — paper-space → pixel rect mapping
- Add paper_canvas_view() in view.rs:
Stack of PaperSheet + one Paper widget per Viewport entity,
positioned with Space offsets from viewport_screen_rect()
- Update VIEWPORT_WIDGET_PLAN.md: mark Steps 1–4 done, document remaining work
