4 * For performance reasons 3 renderers are exported for both MD and 32x modes:\r
5 * - 16bpp line renderer\r
6 * - 8bpp line renderer (slightly faster)\r
7 * - 8bpp tile renderer\r
8 * In 32x mode:\r
9 * - 32x layer is overlayed on top of 16bpp one\r
10 * - line internal one done on PicoDraw2FB, then mixed with 32x\r
11 * - tile internal one done on PicoDraw2FB, then mixed with 32x\r
