Hehe. On the one hand, I'm sorry it caused you frustration... on the
other hand, I'm glad it works. :-)

Every header file we install should #include enough other headers to
define all of the types it uses, absolutely. I'm not sure whether
there's much point in separating the XCBImage bits that use SHM from
those that don't, though.

It seems like a fine new test to add. I tried it out and sure enough, it
didn't work if I changed "ZPixmap" to "XYPixmap" in the source. I
fiddled with it a bit in GDB, but I got bored. :-)

Please do commit, though I'd suggest changing the program's name.
"lissajoux.c", perhaps, so that I'll never be able to type it correctly,
