Code review comment for lp:~oif-team/grail/trunk.glue

Two more patches, further enhancing the unity gesture experience. The first one fixes a problem with the rewritten recognizer, and the second finally gives very clear and distinct recognition of all of drag, pinch and rotate.

Tested in unity and eog. Rotating the picture is effortless, with no side effects. Pinching to zoom is effortless (although eog seems to have some problems there). Dragging with one or two fingers (touchscreen) works just fine, no side effects.

IMHO, this is the best linux gesture experience I have had so far.

Enjoy,
Henrik
