1708 *
1709 * This command takes an optional variable-length list of clipping
1710 * rectangles after the body of the command. If no rectangles are
1711 * specified, there is no clipping region. The entire destRect is
1712 * drawn to. If one or more rectangles are included, they describe
1713 * a clipping region. The clip rectangle coordinates are measured
1714 * relative to the top-left corner of destRect.
1715 *
1716 * This clipping region serves multiple purposes:
1717 *
1718 * - It can be used to perform an irregularly shaped blit more
1719 * efficiently than by issuing many separate blit commands.
1720 *
1721 * - It is equivalent to allowing blits with non-integer

1723 * of a source, for example, by specifying a larger
1724 * destination rectangle than you need, then removing
