Program reproducing the problem with RGBA mode.
The packed RGBA Xv mode (id 0x41424752) gives weird results when used
on a PPC machine with a Radeon 9200 graphics card (Mac Mini). The green
component is decoded as expected, but the red and blue are read twice from
each word, giving half the X resolution.
I've attached a program reproducing the problem. It divides the window
into a 3x3 grid, painting the squares along the diagonal in solid red,
green, and blue, respectively. Which is to say, the expected result is this:
R__ (R = red, G = green, B = blue, _ = black)
_G_
__B
Instead, what you get is this
RR_
_G_
____BB
(The blue square ends up outside the window, so it isn't seen.)
