interpType defines how the interpolation between two states is performed.
* SnapshotBoth: Stores two snapshots, the previous animation before interpolation begins and the target state at the
interTarget frame. Then during the interpolation period the two snapshots are interpolated to produce smooth motion between them.
* SnapshotPrev: Stores a snapshot of the previous animation before interpolation begins. However the target state is
evaluated dynamically. During the interpolation period the previous snapshot is interpolated with the target pose
to produce smooth motion between them. This mode is useful for interping into a blended animation where the actual
blend factor is not known at the start of the interp or is might change dramatically during the interp.
