e6ed58f6c5 Better implementation of the new greyscale algorithm. A bit faster (+2% on iPod and Archos, +7% on Iriver H1x0), and more straightforward. * Fixed garbage display when a plugin switches on the overlay before drawing anything.

71dc284b5d New algorithm for grayscale buffer updates which is faster for large buffer depths. Speedup (unbuffered, depth==32): +8% on H1x0, +17% on Recorder (depth==24), and +83% on iPod Mini.

c214e7bb0c Grayscale library ported to the grayscale iPods, first version. Added C reference versions of gray_update_rect() for both horizontal and vertical pixel packing. gray_update_rect() and gray_ub_gray_bitmap_part() not yet assembler optimised. Grayscale screendump doesn't work yet. * Fixed button assignments for iPod in grayscale.c
