  • Alpha alway output to 0.8 cause reftest error.
  • On TextureRect case, texture coordinate should be size of buffer instead of (0,1). This causes reftest error as well.
  • Still have some reftest errors on fennec

  • Study and trace nsIMemoryReporter framework, which collects the statistic of CPU heap, and check how gfxMemoryImageReporter(relatives to TextureClient/TextureHost/SurfaceDescriptor), and gfxSurfaceMemoryReporter( which relative to gfxASurface's allocation activities) deployed. Will use them to extend some tool to get more clear data and relationship between GPU memory and gralloc.

• bug 931733 - Ease vendor porting of HAL_PIXEL_FORMAT_XXX for color format conversion./solomon
  • Due to GrallocImage.getAsSurface() seems used by video thumbnail and WebGL's canvas, ChiaJung's work in 880114 can be levaraged for this bug, which converts specified YUV color to RGB with GPU in upstream path, and then remove all the code in GrallocImage.getAsSurface(), after making sure if there no possible callers of GrallocImage.getAsSurface(),
