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
