When switching to a USD camera, the orbit pivot was set from
GfCamera::GetFocusDistance() which is a depth-of-field attribute
that defaults to 5 scene units regardless of scene scale.
InitCameraNavigation() now computes the scene bounding box centroid,
projects it onto the camera view ray to get a proper orbit distance,
and calls SetFocalPoint/SetDist to place the pivot correctly.
Added SetDist() setter on ViewportCamera to support this.

- Add edit-target layer combo at top of Scene Hierarchy panel (always
visible when stage loaded — session, root, sublayers); routes through
LayerManager::SetEditTarget so StageEditor ET checkboxes stay in sync
- Replace custom Create Sublayer modal with native SaveFile dialog;
LayerManager::CreateNewSublayer creates the file on disk, inserts it
at the top of the sublayer stack, and activates it as edit target

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).

- SaveStage: explicitly call rootLayer->Save() before m_stage->Save() to
ensure root-layer metadata (subLayers field) is always written to disk
- SaveUsdFile: redirect to SaveAs when the root layer is anonymous so
Ctrl+S on an in-memory stage no longer silently does nothing
- SaveUsdFileAs: call RefreshManagers() after SaveStageAs so LayerManager
stays in sync with the newly opened file-backed stage; without this,
sublayers added after a Save As went to the old stale stage and were lost
- LayerCreateCommand::Execute: use GetSublayers() (sublayer-local indices)
instead of GetLayerStack() (full-stack indices) to record m_insertedIndex,
fixing undo of add-sublayer removing the wrong layer

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

- Replace all text buttons with SVG icon buttons (skip-back, step-back,
play-back, play, pause, step-forward, skip-end)
- Add rewind: separate play-backward button that flips direction
- Add loop mode button with submenu (Loop / Bounce / Off)
- Loop wraps at boundaries; Bounce reflects direction (ping-pong)
- Start/end frames moved to flank the scrub slider as plain numbers
- New icons: play-back.svg, loop.svg (FA repeat), bounce.svg (FA exchange-alt)
