Ctrl+click toggles prim selection; Shift+click range-selects using a
per-frame visible-order list. Multi-selection is broadcast to the viewport
via a new SetOnPrimsSelected callback so Hydra highlights all selected prims.
Adds a 5th table column showing each prim's SdfSpecifier (def/over/class)
with colour coding. 'over' prims are shown in orange to make overrides
immediately visible.
Visibility icon updated: invisible prims show EyeSlash in orange instead
of grey. Ctrl+H / Shift+H keyboard shortcuts hide / show all selected prims.

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.

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.

Rotate manipulator — correct axis bug:
- Object-space delta axis was set to initRot.GetRow3(axis) (a parent-space
vector) then applied in the prim's local frame via deltaM * initRot.
These frames are mismatched: the axis must be the canonical e_a so that
Rot(e_a) fixes e_a and the prim rotates purely about its own axis.
Fixed to use the canonical axis for both spaces; only composition order
differs (deltaM * initRot for object, initRot * deltaM for world).
Gizmo pivot placement:
- ComputeGizmoPivot() used the bounding-box centre (geometry centroid),
placing the gizmo at the wrong location for any non-centred prim.
Replaced with parentToWorld.Transform(translate + pivot) from
XformCommonAPI::GetXformVectors — the authored pivot point in world space.
Fallback for incompatible op stacks uses worldMatrix.ExtractTranslation().
Property panel:
- Show pivot (X/Y/Z) as read-only row below Scale, populated from
XformCommonAPI::GetXformVectors each frame.
- Removed active-rotate-axis display (was added and then removed per request).
