- *
- * Emulate3Button support code
- *
- **********************************************************************/
-
-
-/*
- * Lets create a simple finite-state machine for 3 button emulation:
- *
- * We track buttons 1 and 3 (left and right). There are 11 states:
- * 0 ground - initial state
- * 1 delayed left - left pressed, waiting for right
- * 2 delayed right - right pressed, waiting for left
- * 3 pressed middle - right and left pressed, emulated middle sent
- * 4 pressed left - left pressed and sent
- * 5 pressed right - right pressed and sent
- * 6 released left - left released after emulated middle
- * 7 released right - right released after emulated middle
- * 8 repressed left - left pressed after released left
- * 9 repressed right - right pressed after released right
- * 10 pressed both - both pressed, not emulating middle
- *
- * At each state, we need handlers for the following events
- * 0: no buttons down
- * 1: left button down
- * 2: right button down
- * 3: both buttons down
- * 4: emulate3Timeout passed without a button change
- * Note that button events are not deltas, they are the set of buttons being
- * pressed now. It's possible (ie, mouse hardware does it) to go from (eg)
- * left down to right down without anything in between, so all cases must be
- * handled.
- *
- * a handler consists of three values:
- * 0: action1
- * 1: action2
- * 2: new emulation state
- *
- * action > 0: ButtonPress
- * action = 0: nothing
- * action < 0: ButtonRelease
- *
- * The comment preceeding each section is the current emulation state.
- * The comments to the right are of the form
- * <button state> (<events>) -> <new emulation state>
- * which should be read as
- * If the buttons are in <button state>, generate <events> then go to
- * <new emulation state>.
