TODO:

make sure disabling (aka not using) render buffer works
- allow us to choose which buffer to render onto the screen (i.e. debug buffer)
temp alloc audit
memory arena audit
create base engine (CS230 engine)
create scene & scene manager system
update Model import to work with MaterialLibrary
update Model import to import specular map
write tests
decouple input system from gameplay
custom logger and allocator - give it a try
revisit parser using Text File Handler
group sending data to GPU (shaders and such) - more uniform buffers, batch-sending lighting uniforms to shaders (per scene, per frame, per draw)
refactor uniform buffers
- work with enums instead of strings
- better API
particle systems
animations

Engine

engine initializes all systems and controls flow
- Systems: Graphics, Input, Scene, Events
- calls init, update, render, exit
- engine shutdown Scene system
manages active scene and transitions between scenes Scene
manages entities in scene
- one or more entity containers; group objects by functionality
- Containers: opaque meshes, blendable meshes, lights, skybox* (only ever 1 skybox at a time), cameras* (can be multiple but only 1 is active)
Scene Load & Init: everything before the main loop basically
- Load: allocating memory for entities, fetching data from library or loading from file. What needs to be done once per scene no matter how many times we restart?
- Init: setting initial values for entities and scene. what needs to be reset when scene is restarted?
Scene Update & Render/Draw: everything in the main loop
- (input) -> update -> draw
- Draw (per frame):
  - first, render shadow maps for lighting
    - set up shadow viewport, frame buffer, etc
    - render to texture/cubemap
  - second, render opaque meshes using lighting
    - set up render viewport, frame buffer, etc
    - send dirty camera view and projection matrices to uniform buffer
  - third, render skybox
  - fourth, render blendable meshes
  - fifth, draw to the screen
Scene Unload: everything after main loop
- what needs to be manually shutdown? what can be safely tossed when the game closes?
