okular/core/rotationjob.cpp
Tobias Koenig a490cc0cd7 Add the following functionality:
* Bring QPixmap* back to make Albert happy ;)
 * Store only one QPixmap per page/size and rotate it directly
 * Rotate ObjectRects (boundary)
 * Rotate Annotations (point coordinates)
 * Don't reload pixmaps, ObjectRects and annotations on rotation
