-/* 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.

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. + */ +void pixman_disable_out_of_bounds_workaround (void); + +/* + * Trapezoids + */ +typedef struct pixman_edge pixman_edge_t; +typedef struct pixman_trapezoid pixman_trapezoid_t; +typedef struct pixman_trap pixman_trap_t; +typedef struct pixman_span_fix pixman_span_fix_t; +typedef struct pixman_triangle pixman_triangle_t; + +/* + * An edge structure.
