TPEGFX/2017-Q1

GFX Topics(from high to low priority)

• gfx Stability
• Quantum Rendering
• Canvas 2D perf(google sheet/streaming)
• DisplayList(layout related work)
• Paint correctness(buglist)
• Any layout works, ex: perf/CSS properties

Goal

Ethan Lin

• nsDisplayBorder conversion
  • Enable more border properties (radius, color)
  • Testing
    • Turn on pref for some reftest
  • Debug Tool
    • Identify which layer is converted layer (not PaintedLayer)
  • Simplify properties conversion
    • gfx:Rect -> WRRect -> WrRect
  • Convert other items
• Import ContentClient to WebRenderPaintedLayer
  • Import SingleTiledContentClient first
  • Rotation Buffer - Need to push two sub rect to WR

Jerry Shih

• WR external image
  • update compositable, textureHost and textureSource for new WR thread model(WR render and WR backend are not at IPC receiver thread)
  • handle shmem in WR(upload to gl texture in WR)
  • support subimage for wr add_image api
  • support GL_IOSurface ( https://github.com/servo/webrender/issues/642 )
• WR software backend
  • TBD

Morris Tseng

• Using CanvasClient for canvas
  • Share MacIOSurface
    • WebRender need handle TextureRect in shader. (texture coordinate, shader code...etc)
  • Share ANGLE surface
    • Need to investigate how to translate DXGI to angle gl texture.
  • Handle y-flip

• Convert nsDisplayBullet
  • Create BulletLayer
  • Send Bullet attributes to webrender

Peter Chang

• OMTA
  • convert nsDisplayTransform and nsDisplayOpacity(TBD)
  • dispatch animation/animationdata to compositor for sampling
  • Works in compositor side
    • save animation data based on related div(or containerlayer)
    • sampling animation during composition
    • replay framedata to WR with new animation
    • Add support to Webrender(opacity and scaling)
  • Support OMTA testing flow

   The followings related to testing of OMTA
   nsDOMWindowUtils::GetOMTAStyle()
   SetTestSampleTime()
   LeaveTestMode()
