#14602 Contour map: Keep interactive panning when reloading a project

Browse Source 
Viewer::setView() moves the camera to look straight at the point of interest. Panning does not move the point of interest, so this discarded the camera position restored from the project file.

Only reset the view direction if the camera is not already oriented top-down, which is the case when a contour map has been rotated by a linked 3D view.
