Description:
Transform a set of data
coordinates into world coordinates using a transformation stored in the database. The picture
identifier signifies which picture contains the required transformation structure. If this identifier is
negative then the current picture is used. If no transformation structure is found then the identity
transformation is used, i.e. the world coordinates equal the data coordinates.
