Summary

When using animated world-aligned textures:

• They don't perfectly align to the block (this may not be a bug)
• There are weird strips that don't match up, maybe weird off-by-one errors

Steps to reproduce

Test mod: gromit.zip

1. Enable block bounds for alignment (F4)
2. Place some gromit:* nodes.
3. Try to make sense of it.
