1629 * SVGA_3D_CMD_BLIT_SURFACE_TO_SCREEN --
1630 *
1631 * This is a blit from an SVGA3D surface to a Screen Object. Just
1632 * like GMR-to-screen blits, this blit may be directed at a
1633 * specific screen or to the virtual coordinate space.
1634 *
1635 * The blit copies from a rectangular region of an SVGA3D surface
1636 * image to a rectangular region of a screen or screens.
1637 *
1638 * This command takes an optional variable-length list of clipping
1639 * rectangles after the body of the command. If no rectangles are
1640 * specified, there is no clipping region. The entire destRect is
1641 * drawn to. If one or more rectangles are included, they describe
1642 * a clipping region. The clip rectangle coordinates are measured
1643 * relative to the top-left corner of destRect.
1644 *
1645 * This clipping region serves multiple purposes:
1646 *
1647 * - It can be used to perform an irregularly shaped blit more
1648 * efficiently than by issuing many separate blit commands.
1649 *
1650 * - It is equivalent to allowing blits with non-integer
1651 * source coordinates. You could blit just one half-pixel
1652 * of a source, for example, by specifying a larger
1653 * destination rectangle than you need, then removing
1654 * part of it using a clip rectangle.
1655 *
1656 * Availability:
1657 * SVGA_FIFO_CAP_SCREEN_OBJECT
1658 *
1659 * Limitations:
1660 *
1661 * - Currently, no backend supports blits from a mipmap or face
1662 * other than the first one.

1688 * these formats natively, the SVGA3D device will provide an emulation
1689 * which should be invisible to the guest OS.
1690 *

1693 * operations in software depending on the capabilities of the
1694 * available physical hardware.
