This patch:
- Makes the following substitutions (plus necessary namespace qualifiers:
gfxImageFormat::ARGB32 --> SurfaceFormat::A8R8G8B8_UINT32
gfxImageFormat::RGB24 --> SurfaceFormat::X8R8G8B8_UINT32
gfxImageFormat::A8 --> SurfaceFormat::A8
gfxImageFormat::RGB16_565 --> SurfaceFormat::R5G6B5_UINT16
gfxImageFormat::Unknown --> SurfaceFormat::UNKNOWN
- Changes gfxImageFormat to be a typedef to gfx::SurfaceFormat. This will be
removed soon.
- Removes gfxCairoFormatToImageFormat() and gfxImageFormatToCairoFormat() and
replace calls to them with CairoFormatToGfxFormat() and
GfxFormatToCairoFormat().
- Removes ParamTraits<gfxImageFormat>.
- Add namespace qualifiers to SurfaceFormat instances where necessary.
