Fully invalidate for non-identity and non-translate transforms

For RenderBox with certain transforms, incremental invalidation
is not applicable, because the difference between the old bounds and
new bounds doesn't cover all area needing invalidatin.

Full invalidate in the case.

This is a quick but not optimal fix to the bug, but totally fixing it
needs PaintInvalidationState to be transform-aware which would be a
much bigger change (or changes) not suitable to merge to M39 to fix
the regression.
