pixman supports RGBA (r8g8b8a8 and r8g8b8x8) since 2011, because it's
used on big-endian architectures as well as being a requirement for
OpenGL ES 2.0.

this means that it should be possible to feed a GdkPixbuf pixel buffer
to a pixman_image_t internally back and forth without copies, or, even
better, to replace the GdkPixbuf internal storage and pixops with
pixman_image_t and pixman operators. it should also be possible to
create a tiled buffer composed by pixman_image_t tiles for large image
data.

ciao,
 Emmanuele.
