  * TODO:
- * - add 3d orientation widget to gooey
- * - lighting
- * 	- test adding more lights
+ * - renderer
+ *	- move hexgrid buffer functions from renderer to hexgrid
+ *	- move hex functions from hexgame.cpp to hexgrid
+ *	- add prefix to interface function names for eg) gooey.h, renderer.h
+ *	- check over renderer, camera, gooey init after changes
+ *	- pass in frame time to camera movement functions to decouple speed from framerate
+ *	- attempt to fix bug with starting camera xform
+ *	- test camera speed when moving with composite vector
+ *		- may be fixed?? need to test by examining camera position between frames
+ *			and compare the distance
+ *	- add 3d orientation widget to gooey
+ *
  * - implement texturing to reduce the number of meshes generated by assimp
  *   	from materials (currently creates a sepereate mesh per material)
  *   - need to do UV mapping on models, and parse UV data in shader
- * - move renderer globals to render_state object
  * - map generation
  * - pathfinding
  * - assimp animation
  * - replace aixlog with custom logging iostream?
- * - fix vector normalization in renderer.cpp when moving in 2 directions
- *	- may be fixed?? need to test by examining camera position between frames
- *		and compare the distance
- * - add prefix to interface function names for eg) gooey.h, renderer.h
- * - move hex logic to new file (hexgrid.h) to leave only init glue in a main.cpp
- *		- move SDL input callbacks somewhere too?
  * - think about combining mesh data and render_group data to save some memory
  *		- actually don't need to save the vertex/normal buffers after passing
  *			to opengl
