[PATCH v2] Add regression test for button event state for touch emulation

Mon Jul 9 17:13:15 PDT 2012
When a touch begin is pointer emulated, the initial motion and button
press events should not have the first button set in the button mask.
The button mask represents the state of the buttons *before* the event.
