Some Implementation Notes
REGIONS: Regions are clipping rects associated with a GC. Since
multiple Drawable's can and do share GC's (they are hardware cached)
In order to select clip rect's into GC's, they must be writeable. Thus,
any consumer of the 'gfx' library must assume that GC's created by them
will be modified in gfx.
