Review request for Okular.


Description
-------

This patch adds processing of QTabletEvents to the PageView class. Basically a graphics tablet will behave exactly like a mouse except while creating an annotation. When creating an annotation, the higher precision position of the QTabletEvent is used and this results in smoother free-hand annotations (See the attached image for a before and after comparison).  With this patch in place it's possible to create a nice looking signature in an Okular document using a graphics tablet.

Testing
-------

* The creation of annotations using the wacom pen (smooth freehand annotations)
* The creation of annotations using the mouse (no change)
* The operation of the annotations menu using both the mouse and the wacom pen (pen behaves just like the mouse).


Thanks,
