This patch set on top of GPU ISP patches reduces CPU time spent in
processing statistics by about a half.

Changes in v3:
- Rectangle::croppedBy() dropped, already available methods used instead.
- The cropping is applied also in CPU debayering for consistency.

Changes in v2:
- Safer implementation of Rectangle::croppedBy() as suggested by Kieran.
- Test added for Rectangle::croppedBy().
- The comment about not passing x,y clarified.
