Platform/2009-Q3-Goals: Difference between revisions

Revision as of 18:16, 23 June 2009

These are items that affect the entire team and each of us must endeavor to complete.

Resolve multiprocess graphics issues.
- Decide & implement how image decoding and caching will work in a multiprocess world. (bholley)
- 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)
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
- perf improvements for glyph rendering
- 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
- Source clipping? (would improve efficiency of border-image, see current nsIImage::Extract() hack)
- Supersampling to eliminate curve seams? see bug 466572
Implement prototype of OpenType font-variant extensions on Win7/Vista (nattokirai)
Implement support for unicode-range descriptor (nattokirai)
Crude implementation of SVG font support (nattokirai)
Image decode on demand (Joe?)

Keep working on CSS WG duties (dbaron, fantasai)
Clean up some block layout code (remove float cache, remove float continuations) (fantasai)
Some working examples of SVG text using CSS text layout (ehsan)
SVG/SMIL bug fixes and features (birtles)
An implementation of SVG pointer-events for HTML (jwatt)
Get some of our tests into the official SVG test suite in a reftest-like format (jwatt)

Rapidly resolve any critical issues uncovered by the Firefox 3.5 release (doublec, mgregan, cpearce)
Improve performance in some significant way (e.g., be able to drop frames without decoding them) (doublec, mgregan, cpearce)

Complete 64-bit Mac OS X port that runs on Mac OS X 10.6.
Be prepared for Mac OS X 10.6 on all branches.
- Notify QA of seed releases.
- Track any major regressions.

Improve event handling and firing
- Stabilize our mutation event handling
- Improve our platform event firing (order)
Improve text attribute support
- Improve performance
- Include embedded accessible text attributes
Improve complex table and tree grid accessibility
