TransformMatrix is a convience class to maintain a complete Transform in a single location. It maintains a rotation Matrix, a Vector for translation and a float for scaling.
This allows you to completely transform a point (Vector) in one place.
The class contains the usual get/set methods for the various fields, including passing in a Quaternion and having that converted. It also includes mathematical methods for multiplication.
The applyToSpatial method allows you to set the Transform of a Spatial automatically.
