Review request for Okular.


Changes
-------

Rebase to current frameworks branch

Now that pinch-to-zoom support has landed in 'frameworks' (in 9d90a08ef5e22d682a5a5004128f72d1a5a84aff ) some infrastructure code for gesture capturing can be removed.


Repository: okular


Description
-------

With this patch you can rotate pages by touching your touchscreen with two fingers and then rotating the fingers.  No fancy animation is implemented; all this patch does is call slotRotate[Counter]Clockwise when
the corresponding Qt gesture is triggered.

Sorry for again posting patches against the 'frameworks' branch.  This patch is trivial to backport to the master branch, and as far as I understand Qt, it should work there just the same.  Only it doesn't -- no gesture events are ever received.  Feel free to ignore this patch until 'frameworks' has been merged into the master branch.


Diffs (updated)
-----

  ui/pageview.cpp 339ba69

Testing
-------

Works on my ThinkPad Yoga 12 with today's Debian testing.


Thanks,

Oliver Sander
