Took me long enough, but I finally figured out a solution to some annoying bugs. I may consider adding the new sprites as an option later, but SF will continue using the legacy sprites for the time being. It's an easy way to tell them apart now.
Changelog:
- Fixed an issue where SF wouldn't be aligned in zoomtubes
- Fixed an issue where jumping too quickly after flying or quick-descent would skip a P_IsObjectOnGround check
- Removed a redundant script and halved another section
