Only supported when RECT_PRIMITIVE feature bit is st. COUNT state words follow. These are literally written to state space at the provided offset, after which the offset is increased. If the FIXP bit is set, a conversion from 16.16 fixed-point to 32-bit floating point will happen. If COUNT is zero, it is interpreted as 1024 (the maximum value + 1). Draw rectangles with the 2D engine. Up to 256 rectangles can be rendered with one command. After the header follows one padding word, and after this the specified amount of rectangles follow in (top,left) (bottom,right) format. Rectangles can have every size from one pixel to the size of the entire image, bounded by the clipping rectangle. In the case of drawing lines, the (top,left) and (bottom,right) will be used as inclusive endpoints of the line. Number of rectangles to be rendered with this command. Top left coordinates are inclusive. Bottom right coordinates are exclusive. In case of a triangle strip or other concatenated primitive, this is the actual number of lines or triangles to render. Make sure this number is not too low, nothing else will be fetched. So, make sure that the last command in the new command buffer is either an END, a LINK, a CALL, or a RETURN.
