Merged requested to merge mwestphal/vtk:fixVRRendererResetCamera_backports into release
In VR, resetting the camera would place the object at floor level. For this reason, a translation was added to bring the object closer to eye level. However, this translation only worked if the view up direction (the direction of the top of the head) was +Y. This commit takes into account the current view up direction to always bring the object to eye level.
backport of !9719 (merged)
