1615 *
1616 *    This is a blit from an SVGA3D surface to a Screen Object. Just
1617 *    like GMR-to-screen blits, this blit may be directed at a
1618 *    specific screen or to the virtual coordinate space.
1619 *
1620 *    The blit copies from a rectangular region of an SVGA3D surface
1621 *    image to a rectangular region of a screen or screens.
1622 *
1623 *    This command takes an optional variable-length list of clipping
1624 *    rectangles after the body of the command. If no rectangles are
1625 *    specified, there is no clipping region. The entire destRect is
1626 *    drawn to. If one or more rectangles are included, they describe
1627 *    a clipping region. The clip rectangle coordinates are measured
1628 *    relative to the top-left corner of destRect.
1629 *
1630 *    This clipping region serves multiple purposes:
1631 *
1632 *      - It can be used to perform an irregularly shaped blit more
1633 *        efficiently than by issuing many separate blit commands.
1634 *
1635 *      - It is equivalent to allowing blits with non-integer
1636 *        source coordinates. You could blit just one half-pixel
1637 *        of a source, for example, by specifying a larger
1638 *        destination rectangle than you need, then removing
1639 *        part of it using a clip rectangle.
1640 *
1641 * Availability:
1642 *    SVGA_FIFO_CAP_SCREEN_OBJECT
1643 *
1644 * Limitations:
1645 *
1646 *    - Currently, no backend supports blits from a mipmap or face
1647 *      other than the first one.
