Nicholas Nethercote 6673e03780 Bug 1209812 (part 1) - Remove casts between cairo_format_t and gfxImageFormat. r=nical.
cairo_format_t and gfxImageFormat have their equivalent constants in the same
order, so you can just cast between them, which is kind of nasty.

This patch replaces all such casts with explicit conversions via calls to new
conversion functions. These functions will be removed in a subsequent patch.
