Subject: * fixes mantis 3259 * I'm concerned however that the 'minimum fly
 height' should really be implemented in ScenePresence and not in the specific
 physics plugin so that all of the physics plugins can take advantage of it
 and if desired, a person could swap out the 'minimum fly height'
 functionality with other functionality.
