845 * for historical reasons.
847 * There used to be a bug in the X server where it would rely on
848 * out-of-bounds accesses when it was asked to composite with a
849 * window as the source. It would create a pixman image pointing
850 * to some bogus position in memory, but then set a clip region
851 * to the position where the actual bits were.
853 * Due to a bug in old versions of pixman, where it would not clip
854 * against the image bounds when a clip region was set, this would
855 * actually work. So when the pixman bug was fixed, a workaround was
856 * added to allow certain out-of-bound accesses. This function disabled
859 * Since 0.21.2, pixman doesn't do these workarounds anymore, so now this
860 * function is a no-op.
