pixman_region_union_rect(), contains: if (!width || !height) return PIXMAN_REGION_STATUS_FAILURE; Which seems clearly wrong to me. It should be something like return pixman_region_copy(dst, src);
2005-08-22 Owen Taylor <otaylor@redhat.com> * src/pixregion.c (pixman_region_union_rect): When width/height are 0, copy the src to the dest, don't just return. (#3017)
