TRX bug: varying behaviour of HUD pickups if the inventory/pause screens is opened

[aredfan]

The OG behaviour of HUD sprites is it pauses when the inventory is open, and resumes displaying when the inventory is closed. With that in mind, I've created these tables to help outline the issue with sprite and 3d pickups in both TRX games.

*Opening the inventory/pause screens doesn't exactly pause the 3d pickup, it merely stops at the next part of the animation. Try pausing when the pickup is still moving into the screen, when it's rotating, and when it's moving away from the screen to see what I mean.
