| /* Executive Summary: This function is a no-op that only exists |
| * for historical reasons. |
| * |
| * There used to be a bug in the X server where it would rely on |
| * out-of-bounds accesses when it was asked to composite with a |
| * window as the source. It would create a pixman image pointing |
| * to some bogus position in memory, but then set a clip region |
| * to the position where the actual bits were. |
| * |
| * Due to a bug in old versions of pixman, where it would not clip |
| * against the image bounds when a clip region was set, this would |
| * actually work. So when the pixman bug was fixed, a workaround was |
| * added to allow certain out-of-bound accesses. This function disabled |
| * those workarounds. |
| * |
| * Since 0.21.2, pixman doesn't do these workarounds anymore, so now this |
| * function is a no-op. |
