Hello,
the "problem" that XV does not work with SHM in some combinations
http://www.xfree86.org/pipermail/xpert/2002-February/015507.html
is also true for the very popular testxv.c program.
http://www.cs.uni-potsdam.de/~wertmann/xv/
(All Linux video players used it as startpoint, and maybe Xfree
developers too, this is the reason why I post it here)
This patch makes testxv work even with "uncommon" video
resolutions (like 350x13)
