Thank you for this addition. I will need some more time to think about
that. In XWindowBuffer the default visual gets used a lot, maybe we need
to adjust that as well. Why not get that actual used visual for that
Another question is why art gets the bits per pixel not from the visual,
but from an image. And why isn't that value passed on to the
XWindowBuffer? artcontext_setup_draw_info could use the handed in bpp
value to set that value in the selected draw_info.

I really need to understand all of this in more detail. But most likely
this will have to wait until after my upcoming holiday. (I will be away
for the next two weeks)
