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

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.

Milan Zamazal (2):
  libcamera: geometry: Add Rectangle::croppedBy
  libcamera: software_isp: Reduce statistics image area
