- border support in layers (9 part layers) - this should let us hardware accelerate border type effects better
- cairo-gstate-backend for quartz and D2D
- accelerated layers on linux
- switch away from xlib to cairo-gl and image backends on linux
- integrate cairo-gl for canvas on Mac and Linux (and maybe WinXP with ANGLE?)
- better qcms ICCv4 support
- themeing using GetThemeBitmap() - bug 561265
- Hardware accelerated plugin layers on windows
- Layerize all remaining containers, namely SVG mask/clip-path/filters
- Component alpha rendering using white and black source surfaces (if we don't get it into FF4)
- CSS 3D transforms
- Multiple content processes feeding layer trees to a separate compositing process
- Animation of layer properties offloaded to the compositing process
