I have a display now and it is really fast! However clipping doesn't
work as it should. It doesn't crash but it makes graphics a bit blurry
if active, and so is mouse pointer. There is no speed gain with
clipping.

hacky c way .. but then I looked into ipu.h from mx53 driver. It
basically does everything automatically .
