Bug 1222171 - Re-establish equivalence between gfxImageFormat and cairo_format_t. r=mstange.

It would be nice to add static assertions for this equivalence but I don't want
to have to include cairo.h in gfxTypes.h. (Indeed, that's why
gfxImageFormatToCairoFormat and gfxCairoFormatToImageFormat are macros in the
first place).
