[[ ImageCenterRect ]] First attempt - doesn't work as Skia's nine-way bitmap drawing doesn't take into account CTM.
Merge branch 'develop' into feature-center_rect
[[ ImageCenterRect ]] Skia was correct - I was wrong - it works in User Space so adjusted it so destination rect is scaled, not the CTM (works for non rotated images at the moment).
[[ ImageCenterRect ]] Added release note.
Merge branch 'develop' into feature-center_rect
