bugfix: inscript's bug
To fix this I have to first stop incrementally updating screen_bottom1 in the middle of a frame. Now it always has a good value from the end of a frame. I'm also running into some limitations in the test I'd ideally like to write (that are documented in a comment), but I still get some sort of automated test for this bugfix.
