Damien George a081b49d55 extmod/modframebuf: Optimise fill and fill_rect methods. 
Fill is a very common operation (eg to clear the screen) and it is worth
optimising it, by providing a specialised fill_rect function for each
framebuffer format.

This patch improved the speed of fill by 10 times for a 16-bit display
with 160*128 pixels.
