create or destroy regions

## NAME

## ARGUMENTS

- *gc*

## 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 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.
