<pre>For a reason unknown to me, cairo_format_t is much more limited than the many
options Pixman supports.
The _cairo_image_surface_create_with_pixman_format function does let the user
choose a format, but it is not normally exposed.
I can think of many use cases. In particular, my issue was interaction with
OpenGL ES 2.0: I am using Cairo to write to byte arrays which I later turn into
GL textures. However, OpenGL ES 2.0 only support GL_RGBA, whereas Cairo's
CAIRO_FORMAT_ARGB32 is equivalent to PIXMAN_a8r8g8b8. What I really need is
PIXMAN_a8b8g8r8.
Can this API be made public?</pre>
