A subsurface is a region of another surface that may be used either to
restrict the writable area of a context or the readable extents of a
source. Whilst writing, access to the exterior of the subsurface is
prevented via clipping and when used as a source reads from the exterior
of the subsurface are governed via the extend mechanism of the pattern.
