Fabien Freling e7802e30fd Compute src position in quantified coordinates. 
Instead of relying on floating values for the position in the
source image, we quantify all positions with a power of 2.

We lose some precision and the delta step is less accurate, leading in
some offset at the end.

For now the rotation is not correct.

RotateMeFast

This project aims to rotate bitmap images very quickly (around a millisecond).
