 *  - full lighting model
 *  		- add buffer backed storage for light arrays in GLSL
 *  		- remove hard-coded values in full_lighting.frag
+*  		- test buffer backed lights, probably need to pad any scalars/vec3s
+*  		- add point light type with tweakable attenuation parameters
+*  		- see if we can find a way to automate the creation of the LightsBuffer
+*  			padding, maybe not possible without reflection
+*  		- make separate shaders for per vertex, and per pixel/fragment lighting
+*  			see red book chapter 7
+*  		- add a bloom/blur render to texture shader for light sources?
+*  			https://learnopengl.com/Advanced-Lighting/Bloom
+*  - add scene abstrastion for RenderState
 *  - test complex entities
 *  		- need a separate GLBufferToAttribMapping for each mesh on an entity
 *  		- maybe fixed now with MeshBufferType enum and getMeshData()
