MATRICES ARE IN COLUMN MAJOR ORDER (to reflect GLSL)


dependencies
------------

- gl
- glfw3 (included in ext/)
- glew (included in ext/)
- stb_image (included in ext/)
- luajit (included in ext/)
- chipmunk (included in ext/)


ideas
-----

- message system: there is none -- instead you just have a system that
  best does the job you want -- why generic messages? do each thing the best
  way it can be done ('collision' message would just be a collision system that
  stores a dual map of two ids to the collision contact, etc.)

- in edit mode each system has its own window with all entities, when you
  select one it focuses on the right row -- allows system-specific interfaces
  (transform is a tree etc.)

- is the system-data extremely tight coupling right now good?
    - it made it easy to see all the data about, for example, sprites,
      visualize the invariants and make sure they held on *_remove() etc.


todo
----

- easy: make entity_destroyed(ent) be true iff. on 2nd pass of
  destroyed map?

- easy: move window stuff from game into a new window system
  (bg_color, size)

- easy: serialize global physics properties, expose more physics
  functions
