The transformation handler is a set of handlers used for transformation interactions. these handlers are centered at the
origin of the currently selected features and are rendered depending on a) the current mode and b) the current selections
sets capabilities. if one or more selected features are clamp to ground, no Z manipulations will be available and
they will be greyed out. updates to the selection set are handled by the handler. updates to the features (for instance
setting the olcs_altitudeMode on a currently selected feature) is currently not handled.
transformation handlers are only valid for the currently active map (and oblique image).
it is up to the creator to re-create them as needed (map change, image change, external geometry or property change to a selected feature).
In most scenarios, this function must not be called directly and the startEditFeatureSession used instead.
