'''
this class provides a test to emulate one or two TOUCH/TRACK events.
by pressing "ctrl left/right" the TOUCH events will be switched into TRACK events and the
other way around.
by pressing "shift left/right" a second event is created whenever the mousebutton (left)
is clicked.
Note: remove any mouse event handling from your application to avoid emulation issues
For example:
1) avg.MOUSE | avg.TOUCH filters can be safely reduced to avg.TOUCH
2) the current libavg button module breaks the emulation
3) the current libavg Grabbable class breaks the emulation, unless is created with
source = avg.TOUCH parameter
