[cairo] Confused by render to image buffer

[Chris]

Another thing I'm confused about is that the render to image defaults to
BGR format instead of RGB.  I'm not sure how to make it use RGB.  Is
there a function call to set the mode?

I looked a little in the pixman icint.h and icformat.c but there is all
sorts of craziness going on in there.  All the macros inside of macros
is extremely annoying.

For now I just changed pixman_format_create_masks to reverse the
ordering but that doesn't seem like the right thing to do.  Especially
since in icint.h there is at least some notion of BGR and RGB.
