[Bf-blender-cvs] SVN commit: /data/svn/bf-blender [32936] trunk/blender/source/blender/ editors/space_view3d: - when orbiting the view out of camera mode use the ortho/ persp setting of the camera.

Log Message:
-----------
- when orbiting the view out of camera mode use the ortho/persp setting of the camera.
- display the physical size of a ortho camera since, unlike a perspective camera the ortho scale can be converted into a plane with real size.
