This blends two "565"-format bitmaps, including byteswapped ones. All the bitmaps have to have the same memory format. The routine takes about 63ms on a Kaluga when operating on 320x240 bitmaps. Of course, displaying the bitmap also takes time. There's untested code for the L8 (8-bit greyscale) case. This can be enabled once gifio is merged.
