qdrawhelper: optimize fetchTransformedBilinear
When scaling down, there is no need to keep 8 bit accurancy on the position
4 bit is enough and should not be noticable for the human eye.
Also optimize the pure scaling if there is no rotation:
when scaling up, do the average between the top and the bottom row
then use this pre-computation later.
