I wouldn't be very surprised to learn that that is the case.

I haven't tested it at all, so you're already speaking from a more
authoritative position I think. :-)

As far as the idea of converting when transferring to/from the X
server, I think that's what the patches here do (originally written
for the 8bpp case):

	Cairo doesn't have 8-bit pseudocolor support
	https://bugs.freedesktop.org/show_bug.cgi?id=4945

I honestly haven't looked at the issue close enough to made a
judgement call on whether those patches are in the right direction or
not. I'd be glad to hear opinions from people here, (as well as
results from testing these patches for the 24-bpp problem in this
thread).
