913 * There used to be a bug in the X server where it would rely on
914 * out-of-bounds accesses when it was asked to composite with a
915 * window as the source. It would create a pixman image pointing
916 * to some bogus position in memory, but then set a clip region
917 * to the position where the actual bits were.
918 *
919 * Due to a bug in old versions of pixman, where it would not clip
920 * against the image bounds when a clip region was set, this would
921 * actually work. So when the pixman bug was fixed, a workaround was
922 * added to allow certain out-of-bound accesses. This function disabled
923 * those workarounds.
924 *
925 * Since 0.21.2, pixman doesn't do these workarounds anymore, so now this
926 * function is a no-op.
