H1x0: Changed lcd_blit() and the grayscale library to use the same internal format as on archos (1bpp). While the slowdown of the ISR is minimal (the intermediate buffers are in IRAM), the planar grayscale buffer takes only half the space for a given depth, and gray_update[_rect]() and unbuffered drawing/scrolling are faster because less data needs to be moved. It should also make porting of video.rock somewhat easier. * Archos recorders, Ondios: Some slight optimisations of the grayscale library.
