Terminology for graphics driver writers

Clip

``clip'' is graphics jargon that means you can only draw inside some specified rectangle. When drawing an object, if some pixels fall outside the clip rectangle, they must not be drawn to the frame buffer. Some graphics chips implement this in hardware; this is referred to as hardware clipping in this manual. Use the SetClipRegions(D3nfb) function to set the hardware clip regions on the graphics adapter.
