+Description: Avoid large pixmaps
+ It is allowed to try and allocate a pixmap which is larger than
+ 32767 in either dimension. However, all of the framebuffer code
+ is buggy and does not reliably draw to such big pixmaps, basically
+ because the Region data structure operates with signed shorts
+ for the rectangles in it.
+ .
+ Furthermore, several places in the X server computes the
+ size in bytes of the pixmap and tries to store it in an
+ integer. This integer can overflow and cause the allocated size
+ to be much smaller.
+ .
+ So, such big pixmaps are rejected here with a BadAlloc
+ .
