- Fixed a minor bug in the Camera module.
- Added some extra capability to the Movie module.
- The Camera module now has the capability to perform parallel projection by calling the 'parallelProjectionOn' method.
- The Camera at this stage is only capable of zooming towards the rendered object using 'dolly'. However, it appears that 'dolly' cannot be used to perform zooming out.
