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