I have found a need to have view.fov based on the horizontal field of view instead of the vertical field of view. I found a thread dating back to 2009 stating that view.fovtype was placed into a beta (with hfov one of the possible settings), but there is nothing in the current documentation for this setting. Was view.fovtype left out of the final release or is it in there as an undocumented option? (I'm going to try it and see what happens)
Cheers,
