1714 *
1715 * The blit copies from a rectangular region of an SVGA3D surface
1716 * image to a rectangular region of a screen or screens.
1717 *
1718 * This command takes an optional variable-length list of clipping
1719 * rectangles after the body of the command. If no rectangles are
1720 * specified, there is no clipping region. The entire destRect is
1721 * drawn to. If one or more rectangles are included, they describe
1722 * a clipping region. The clip rectangle coordinates are measured
1723 * relative to the top-left corner of destRect.
1724 *
1725 * This clipping region serves multiple purposes:
1726 *
1727 * - It can be used to perform an irregularly shaped blit more
1728 * efficiently than by issuing many separate blit commands.
1729 *
1730 * - It is equivalent to allowing blits with non-integer
1731 * source coordinates. You could blit just one half-pixel
1732 * of a source, for example, by specifying a larger
1733 * destination rectangle than you need, then removing
1734 * part of it using a clip rectangle.

1736 * Availability:
