[x3d-public] Playback controller

[Mike McCann]

Thanks everyone for your suggestions. 

Leonard's advice on having a custom Script node generate the fraction_changed events for the interpolators was the key for getting it to work. A bit of clever programming was needed to merge input from a TimeSensor. 

Max's suggestion will come in handy when I need to do this in x3dom.

I could not get the DVDControllerPrototype from the SAVAGE X3D Examples Archives to work in InstantReality player.

I feel that making a playback controller would be a lot easier if TimeSensor had a set_fraction Input field.

-Mike
