Bounding box right/bottom coordinates are not exclusive (or are exclusive depending on your definition) as was previously thought. This has been verified using a hardware test.

Having this offset causes a regression in the Grubba office peeking cutscene in Paper Mario: TTYD, which is a known to be extremely sensitive to wrong bbox values. I have also tested the removal of the offset against the Puni EFB copy artifacting case, and as expected that does not regress.

This causes hard crashes in Ultimate Spider-Man, another bounding box game. I will report an issue soon.
