MaterialBrowserWidth / MaterialPreviewWidth in preferences.ini, saved
from the live splitter positions on shutdown and restored (clamped to
the splitter ranges) at startup.

Browser column lists all scene materials plus a searchable create-node
list; Show Graph (or double-click) loads a material into the node-graph
work area. The graph shows the entire network including MaterialX
(.mtlx) node graphs, resolving connections through NodeGraph boundaries
via UsdShadeUtils::GetValueProducingAttributes, with layered auto-layout
for nodes lacking authored uiPosition. Canvas navigates viewport-style
(Alt+MMB pan / Alt+RMB zoom) and TAB opens a Nuke-style search popup.
Selecting a node shows a typed property editor (live-apply, one undo
command per edit) and previews that node's output on the shader ball.
The preview renders through its own Hydra engine into a scratch stage
that composes the material via a reference to the source root layer (so
referenced .mtlx materials work), re-renders until progressive delegates
(Arnold/Cycles/Embree) converge, and lights with HDR dome presets
(External/Room/Interior/Sunset; CC0 Poly Haven EXRs fetched at CMake
configure). texture:format is authored latlong explicitly - left
automatic, hdArnold falls back to Arnold's angular fisheye default -
and hdCycles gets a -90 X pole rotation to match Storm's +Y-pole
sampling.
Mutations go through new ICommand subclasses (create shader node,
connect/disconnect attrs). imgui-node-editor is vendored (gitignored)
with a local one-line patch: c_ScrollButtonIndex 1->2 for MMB pan.

Preferences (Edit > Preferences, tabbed General/Animation/Viewport):
- Viewport tab: Default Render Delegate and Color Correction settings
- Persisted to %APPDATA%\UsdLayerManager\preferences.ini
- Render delegate: startup default only (not live-applied to running tiles)
- Color correction: global, applied live to all viewports on change
Render delegate per-viewport:
- Each tile toolbar switches its own delegate independently
- Saved per-tile in viewport_settings.ini; restored on next launch
- Tiles with no saved delegate get the pref default on startup
Color correction global:
- Removed from gear popup; lives in Preferences > Viewport only
- Applied to all tiles on init and on live change from Preferences
Fix InitRenderer always applying m_currentRendererPlugin when set,
rather than skipping when UsdImagingGLEngine auto-selects a default.

ViewportTileSettings struct captures: render delegate, show grid, AA, background
color, bbox mode, ambient-light-only, dome-light flags.
ViewportPanel::SaveSettings() writes a simple INI file (layout + one [TileN]
section per tile) to %APPDATA%\UsdLayerManager\viewport_settings.ini on
Application::Shutdown().
ViewportPanel::LoadSettings() is called at the end of Application::Initialize()
— after the viewport panel is constructed but before the first frame — so the
saved render delegate is picked up by UsdSceneRenderer::InitRenderer() on the
first Render() call. Layout (Single/HSplit/VSplit/Quad) and split ratios are
also restored, creating the correct number of tiles before settings are applied.

Maya-style Graph Editor panel (View > Curve Editor) that fits Catmull-Rom
Bezier curves through USD time samples, allows interactive editing with
tangent handles, and bakes the result back to dense linear samples on Apply.
Key behaviours:
- Left panel lists all animated attributes of the selected prim, decomposed
into per-component channels (translate [X/Y/Z], etc.) with colour swatches
and visibility toggles
- ImDrawList canvas: smooth Bezier polylines, always-visible tangent handle
lines/circles, diamond keyframe markers
- Pan (MMB/Alt+drag), zoom (scroll / Shift+scroll), Frame All (F)
- LMB drag moves keyframes; tangent handle drag reshapes curve with mirrored
or broken handles; box-select for multi-selection
- Double-click canvas adds a keyframe; Delete removes selected keyframes
- RMB context menu: Delete, Flatten, Break/Unify Tangents, Auto Tangents
- Simplify toggle (Ramer-Douglas-Peucker) reduces baked sample count
- Time cursor draggable to scrub the timeline
- UsdNotice::ObjectsChanged listener re-fits clean channels whenever the
stage changes externally (Property Panel edits, Auto-Key, undo/redo),
while preserving channels with unsaved Bezier edits
- Bake is a single undoable AttributeSetCommand (Ctrl+Z restores original
sparse samples); Revert discards in-editor edits without touching USD

- TimelinePanel: Playblast button opens modal with output dir (native
folder picker via IFileOpenDialog), custom resolution (HD/FHD/4K
presets), frame range, and movie export toggle
- UsdSceneRenderer: CaptureFrame() reads pixels from resolved MSAA FBO;
Render() stores last dimensions for off-screen re-render at capture res
- MovieEncoder: streams RGBA frames directly into MP4 using libavcodec/
libswscale (H.264, tries libx264 → nvenc → qsv → amf → openh264)
- Application: CapturePlayblastFrame() re-renders at capture resolution
each frame; opens/writes/closes MovieEncoder inline with the render loop
- FileDialog: BrowseFolder() using Vista-style IFileOpenDialog (COM)
- CMake: FindFFmpeg.cmake locates prebuilt BtbN GPL shared package in
third_party/ffmpeg; links and copies DLLs for main and test targets

Each panel (Stage Editor, Scene Hierarchy, Viewport, Property Panel,
Timeline) now has a checkable menu item under View. Closing a panel via
its X button also unchecks the entry. Stage Info and Demo Window follow
below a separator.

Replace LayerPanel with StageEditorPanel for full sublayer composition workflow:
- Edit target (ET) checkbox on root/session and each sublayer; pen icon header
- Dirty indicator (*) per layer; muted layers remain visible in list
- Drag-drop and Move Up/Down reordering with undo (LayerReorderCommand)
- Add existing sublayer via file dialog; create new sublayer modal
- Fixed LayerReorderCommand::ApplyOrder using full-stack indices on sublayer-local
list (silent remove failure → duplicate insert → USD _ValidateEdit error)
- Fixed muted sublayer visibility: walk GetSubLayerPaths() + FindOrOpenRelativeToLayer
+ m_layerRefs to keep muted layers alive and visible
