Scripting Changes for 4.0d:

* Added VideoKeyframeType enum, Keyframe.Type property, and
VideoMotionKeyframe.Type. These allow scripts to get and set keyframe
interpolation.

* Added Media.Generator property which allows scripts to add key
frames and set presets for generated media.

* Fixed bug where saving a project via script does not reset the
project's dirty flag.

* Fixed bug related to adding envelopes to bus tracks created via
script.

* Fixed bug where VideoBusTrack.MediaType returned
MediaType.Audio. Now it returns MediaType.Video.

* Fixed bug related to setting the curve type for fades... now accepts
Smooth and Sharp curve types.

* Fixed problem where ungrouped events that are split via script
results in a new group which cannot be cleared via script. Events that
were previously grouped still result in grouped splits.

* Fixed problem that scripts could not get or set whether video event
effects are applied before pan/crop operations... added
Effect.ApplyBeforePanCrop property.

* Fixed bug that would occur when video motion keyframes collection
was completely cleared. Now all but the first keyframe are removed in
the Clear method.

* Fixed problem that Smoothness parameter was not previously available
for VideoMotionKeyframes.

* Added RulerFormat.SmpteFilmsyncIVTC constant.

* Hopefully fixed problems related to running a combination of JScripts and
VB scripts.
