Nicholas Nethercote 88696a303a Bug 1209812 (part 6) - Convert all gfxImageFormat values to SurfaceFormat equivalents. r=jrmuizel.
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.
