<member name="offset_h" type="float" setter="set_h_offset" getter="get_h_offset" default="0.0">
The horizontal offset of the camera, relative to the drag margins.
[b]Note:[/b] Offset H is used only to force offset relative to margins. It's not updated in any way if drag margins are enabled and can be used to set inital offset.

The vertical offset of the camera, relative to the drag margins.
