Todo:
- Fix rotation gizmo for scaled meshes
- Implement ray-bounding box picking and determine whether that is enough for our needs or do we need to implement OBB
- Command to create a placeholder entity of a particular type in a file
- Re-write/Overhaul bounding volumes and ray intersection
@ -400,4 +399,5 @@ Done:
* Implement resetting complete transform or just rotation, translation
or scale for selected entity
* Save transformation information when saving entity archetypes
* Implement bounding box visualization
* Implement bounding box visualization
* Fixed rotation gizmo for scaled meshes
