XCreateRegion, XSetRegion, XDestroyRegion - create or destroy regions
Region XCreateRegion(void);
int XSetRegion(Display *display, GC gc, Region r);
int XDestroyRegion(Region r);
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 relative 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.
