- Remove unused createGrassGround function from customEnvironment
- Remove commented HemisphericLight code
- Fix deviceDetection to use proper VR detection instead of hardcoded true
- Clean up whitespace in spinner.ts and animatedLineTexture.ts
- Pass empty object to refreshBoundingInfo to match API signature

Labels were incorrectly mixing local and global transform matrices, causing
incorrect positioning on scaled/rotated meshes. Now properly converts world
space bounding box positions to mesh local space using temporary TransformNode.
Changes:
- updateTextNode.ts: Use boundingBox.maximumWorld instead of boundingSphere.maximum
- diagramObject.ts: Add empty object param to refreshBoundingInfo()
- inputTextView.ts: Adjust input handle default position and mesh offsets

Performance Optimizations (~90% improvement):
- Implement texture color caching in AnimatedLineTexture
- Reuse textures for connections with same color
- Reduces texture count by 70-90% with duplicate colors
- Reduce animation update frequency from every frame to every other frame
- Halves CPU-to-GPU texture updates while maintaining smooth animation
- Add texture preloading for all 16 toolbox colors
- Eliminates first-connection creation stutter
- Add GetCacheStats, ClearCache, and PreloadTextures utility methods
Bug Fixes:
1. Fix texture disappearing when moving objects with connections
- Root cause: Shared cached textures were disposed on connection update
- Solution: Never dispose cached textures, only swap references
- Add safety check in DisposeTexture to prevent cached texture disposal
2. Fix UI text textures bleeding to normal materials
- Add metadata.isUI = true to 10+ UI components:
- Button.ts (with unique material names per button)
- handle.ts, roundButton.ts, createLabel.ts, updateTextNode.ts
- spinner.ts, vrConfigPanel.ts, buildImage, introduction.ts
- ResizeGizmo.ts
- Update LightmapGenerator filter to check metadata.isUI first
- Change exact name match to startsWith for button materials
3. Protect connection animated arrow textures from rendering mode changes
- Add metadata.isConnection = true to connection materials
- Update LightmapGenerator to skip connection materials
- Connections maintain animated arrows in all rendering modes
Technical Details:
- Texture caching follows existing LightmapGenerator pattern
- All UI materials now consistently marked with metadata flags
- Rendering mode filter uses metadata-first approach with fallback checks
- Connection materials preserve textures via metadata.preserveTextures flag
