* Surface visible region in device coordinates. * * num_rects: The number of rectangles in the rect array. If num_rects * is zero the bounds rectangle is used for the visible rectangle. * If num_rects is zero the surface must be completely contained * by the device. * * bounds: The unclipped surface rectangle in device coords. Extends * beyond the device bounds if the surface is not totally on * the device. * * rect[]: An array of visible rectangles in device coords. If num_rects * is non-zero only the region described by these rectangles is * copied to the frame buffer during a flush operation.

* Determine the size of a region.

* Surface client public memory types. Private memory types start with * kIOAccelNumSurfaceMemoryTypes.

* Surface client public methods. Private methods start with * kIOAccelNumSurfaceMethods.
