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