  32 KEY BUTTONS
  33
  34 Continuous button event tracking is complicated by the fact that two different
  35 input sources (say, mouse button 1 and the control key) can both press the
  36 same button, but the button should only be released when both of the
  37 pressing key have been released.
  38
  39 When a key event issues a button command (+forward, +attack, etc), it appends
  40 its key number as a parameter to the command so it can be matched up with
  41 the release.
  42
  43 state bit 0 is the current state of the key
  44 state bit 1 is edge triggered on the up to down transition
  45 state bit 2 is edge triggered on the down to up transition
