Mapping flv video to geometry in Actionscript

To avoid having to use SWF encapsulated video files to map video to geometry in Flash 9, use the flash.media.Video class instead. The following extends the Plane class in the open source Away3D flash library to have a plane with a texture mapped video (flv). The constructor takes the location of the flv file (either a path to the file or as a URL).

This version of the class should now work with Away3D 3.0.0
