-	 * @param srcbuf	the buffer containing the original graphics data

-	 * @note This implementation is slow. Please override this if
-	 *		 your backend hardware has a better way to deal with this.
-	 * @note This implementation requires the screen pixel format and 
-	 *		 the hardware pixel format to have a matching bytedepth.
-	 * @note This is meant for RGB modes only, do not attempt
-	 *		 to use it when running in 256 color mode.
