GFX

  • Research multiprocess graphics issues.
    • Support & participate in Mozilla Electrolysis project. (joe)
    • Resolve how to accomplish hardware accelerated graphics in a multiprocess, sandboxed world. (joe)
    • (maybe) Prototype multiprocess hardware acceleration. (joe)
    • Measure and decide how font metrics caches will work in multiprocess (startup time and memory usage) (joe)
  • Continue hardware acceleration work.
    • Continue work on prototype hardware acceleration to extend it to two platforms total. (joe)
    • Above notes for hardware accelerated graphics in multiprocess & sandboxed world.
  • Improve Cairo software rendering performance. Possibly includes: (jrmuizel)
    • stroke_to_path

    • image scaling performance improvements
    • other things that are slow in cairo that people need sped up (suggestions please!)
  • Improve cairo capabilities. (jrmuizel)
    • high quality downscaling
    • develop a plan to resolve image drawing/EXTEND_PAD mess
    • need Source clipping? (would improve efficiency of border-image, see current nsIImage::Extract() hack) (need some numbers...)
    • (not-likely) Supersampling to eliminate curve seams? see bug 466572
  • Font system enhancements (jdaggett)
    • Refine font feature support spec with prototype implementation
