Merge lp:~bratsche/oif/evince-move-gestures-into-view into lp:~oif-team/oif/evince-gestures-trunk

[Cody Russell]

This branch requires the following first:

https://code.launchpad.net/~bratsche/libgrip/event-routing/+merge/43378

This moves the gesture logic out of EvWindow and into EvView, as well as simply updating evince to work with the libgrip changes in the other merge request.

[lp:~bratsche/oif/evince-move-gestures-into-view]

4213. By Cody Russell on 2011-01-07

Set some #define constants for velocity and angle.
