rockets.h

/*
  Prototype 2
  - 5 levels.
  - GUI that shows some feedback.
  - Interpolated animation.
  - Icons for the buttons maybe.
  - Win / Lose conditions in the simulation.

  - size/used for memory buffers, num/max_num for object arrays.

  Rockets is almost playable!
  @TODO
  - Show thruster selector on thruster node.
  - Integrate entity into sensor node. (selector and make it work)
  - Do the grid area math to support ^
  - More than 1 level.
  - Lose conditions.
  - Animation.
  
  * Try out a flying sauser ship see how much easier that is.

  @TODO, @NOTE, @INCOMPLETE, @HACK, @HARDCODE, @FRAGILE, @CLEANUP
