Add environment and meta gestures

With meta gestures, the gesture starts given a certain number of
fingers, but can then continue even if the number of fingers change.
By configuration, such gestures live on a different priority plane
from normal gestures. To match window manager specs, this patch adds
the environment and meta planes, and add drag, pinch and rotate gestures
initiated with three and four fingers, respectively.
