This changes BKE's fitting code to use `BKE_camera_params_compute_viewplane` instead of `BKE_camera_view_frame`. This allows that code to work with orthographic projection too. Also, two funcs were added to rna's Object, to resp. get the projection matrix of that object (mostly useful for cameras and lamps objects), and return position this object should be to see all (to fit) a given set of points.
