#85 sluggish multitouch gestures fix

[Andrzej Pronobis]

A patch fixing the delay previously required before the scroll or zoom gestures. The patch implements the following behavior:
- two fingers enable the zoom/scroll gestures immediately without any additional delay or lagging
- quick tap using the second finger emits right click
- right click now does not emit left click at the same time

The patch was tested only on Wacom Serial Tablet with touch (penabled) in Lenovo x201t.

Andrzej,

please make a patch against the current xf86-input-wacom git master and post it to linuxwacom-devel@linxts.sf.net so more people can review and test it. Thank you.

The parts about going immediately into scroll/zoom and not sending right click are now fixed in current git but by a patch developed in isolation from these.

Two finger right click still doesn't work but I plan to fix this using the standard 2 finger tap (not a finger down and then tap a second finger that is required now).

I suggest keeping this patch open for a little while longer (until 2 finger tap is fixed in git) and then it can be closed.

There are still improvements needed beyond 2 finger taps if your interested in list of known remaining gesture issues.
