glx: Be more strict about rejecting invalid image sizes [CVE-2014-8093 2/6]
Before this we'd just clamp the image size to 0, which was just
hideously stupid; if the parameters were such that they'd overflow an
integer, you'd allocate a small buffer, then pass huge values into (say)
ReadPixels, and now you're scribbling over arbitrary server memory.
v2: backport to nx-libs 3.6.x (Mike DePaulo)
