I'd still like to see a test case for the people running into slowness
here.

Cairo should already be creating 16-bit surfaces when possible, (for
example in _cairo_xlib_surface_create_similar when given a 16-bit
surface to start with). But cairo wasn't always clever about this, no.

Now, ifthe application is actually handing cairo an ARGB32 image
surface, then that's a totally separate issue, (and the application
should just be fixed to not do that).
