• Sub-texture image optimization (Issue 117)
• Native support for ABGR format (Issue 85)
• Use Pixel Buffer Objects (Issue 118)
• Use OpenGL automatic mipmap generation (Issue 126)
• Geometry optimization:
• Use Vertex Buffer Objects (Issue 119)
• SetLive/ ClearLive MT cleanup (Issue 120)
• Stop using finalize() to cleanup state (Issue 121)
• Collection class usage: (Issue 122)
• Use Set versus List when appropriate
• Use generic Collection rather than j3d-specific classes (e.g., UnorderList)
