* Corrected the h,w calculation for zooming in layercache.cpp.
* Fixed the bug, that x,y camera position result in an screen offset. fixes[ticket:462]
Note: chewie was right, the ExactModellCoordinate object for camera creating is useless(always 0,0,0). I'm believe that we can remove it from the camera constructor but that would mean an api change.
