3dobs TODOs:
 - [x] Help menu
     - [x] About window
 - [ ] File logger
 - [x] Move console to be under objects
 - [x] Don't have the viewport window be scrollable
 - [x] Object rotation with left click + mouse movement (very rudimentary implementation, but works)
 - [x] Camera movement with shift + left click + mouse movement
 - [x] Ability to change active model
 - [x] Hide inactive models
 - [x] Scroll zoom
 - [x] (BUG) Fix some meshes not rotating around their origin point (in actuality, they don't have an origin point and are only rotating around 0.0, 0.0, 0.0)
     - First thing that comes to mind is just rotating them around the center_point of the mesh (which is the bounding box's center point)
 - [x] Default material
 - [x] Toggle box for different zooms
 - [x] Increase max zoom-out
 - [x] Slider for model rotation speed
 - [x] Smaller console area
 - [ ] Better object rotation
 - [ ] Ability to change rotation pivot point (needs raycasting and shit)
 - [ ] There might be memory leaks somewhere (tracked it down to russimp, will have to write my own .obj and .stl readers)
 - [x] Reset object rotation when changing active model
 - [x] Drag'n'Drop models
 - [ ] Config for consistent settings between restarts (home dir preferred)
 - [x] (BUG) when removing a model that's not selected and the selected model is not the last, we select the last one
     - only select the last one if we removed the selected model
 - [x] Use filename for the root node
 - [x] Ship shaders directly in the executable

 - [ ] Bring back the regular camera movement (can maybe be a switch between them) (for later)
