DESCRIPTION
The XCreateRegion function creates a new empty region. The XSetRegion function sets the clip-mask in the GC to the specified region. The region is specified rela- tive to the drawable's origin. The resulting GC clip origin is implementation-dependent. Once it is set in the GC, the region can be destroyed. The XDestroyRegion function deallocates the storage associated with a specified region.
