Detailed Description

Event handler allowing the user to record the animation "path" of a camera.

In it's current implementation, this handler cannot guarantee the final view matrix is correct; it is conceivable that the matrix may be one frame off. Eh--not a big deal! :) TODO: Write the file as we go, not when it's all done. TODO: Create an osgviewer on-screen indication that animation is taking place.
