ICE transfer of FxTree Tracking operator

The compound internally builds a camera frustum and translates fxtree tracking data to 3d data.
Two things you should know before using:

- be sure to align camera and interest Y position before applying the compound. (that's because frustum rotation is not being calculated yet)
- change the image resolution inside the compound to fit your dimensions. (didn't find a way of retrieving image resolution right inside the ice tree)

...being using this one a lot in shots involving simple 2d tracking (no rotation, or hand keyed rotations) for object replacements, prop attachments, etc..

compound will be stored under Tools > Tracking.
