Don't adjust the bounds after a restore with the restore's paired saveLayer's paint.

Don't adjust the bounds after a restore with the restore's paired saveLayer's paint.

It makes no sense for the paint from a saveLayer to effect anything outside its saveLayer/restore block.  But as currently written, we'll adjust the clip bounds just after a restore by that paint.

Turns out the test I wrote for the last CL (which caused this bug) actually had the bug baked into its expectations.  I've updated them and added some notes to explain.
