* This command takes an optional variable-length list of clipping
* rectangles after the body of the command. If no rectangles are

* drawn to. If one or more rectangles are included, they describe
* a clipping region. The clip rectangle coordinates are measured
* relative to the top-left corner of destRect.

* This clipping region serves multiple purposes:
*
* - It can be used to perform an irregularly shaped blit more
* efficiently than by issuing many separate blit commands.
*
* - It is equivalent to allowing blits with non-integer
* source coordinates. You could blit just one half-pixel
* of a source, for example, by specifying a larger
* destination rectangle than you need, then removing
* part of it using a clip rectangle.
