pass for now:
- cast a shadow | can be done using shadow map
- reflection, build on blending, needs stencil magic? | possible with shaders?

wip:
- extend m3d

todo:
- xbox controller
- obj loader
- look at mesa's sources and borrow OSD stuff
- GL error checking and extensions
- split SDL
- draw inhabitants, that would accept a texture id
- fps counter in seperate file, could draw to SDL surface
- remap the keys, so we can fly in the scene

pyramid:
- could do with 2 textures and practice generating and binding textures

gltools:
- could have init() that would load textures for each func, and in each func
  we would have to bind the particular texture
