 *
 *    The blit copies from a rectangular region of an SVGA3D surface
 *    image to a rectangular region of a screen or screens.
 *
 *    This command takes an optional variable-length list of clipping
 *    rectangles after the body of the command. If no rectangles are
 *    specified, there is no clipping region. The entire destRect is
 *    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.
 *
 * Availability:

 *    - Currently, no backend supports blits from a mipmap or face
 *      other than the first one.
