Texture optimizations:

Sub-texture image optimization

Native support for ABGR format
+

SetLive/ ClearLive MT cleanup
+
Collection class usage:
+

Use Set versus List when appropriate
Use generic Collection rather than j3d-specific classes (e.g., +UnorderList)
+

Eliminate memory free lists
Improve picking performance / reduce garbage generation (if +picking does not move into core)
Optimize CanvasViewCache to eliminate redundant operations & +garbage generation
