Axis options for TrackTo LockTrack FollowPath Auto creation of TrackTo constraint from Ctrl-T (old track still an option) Auto creation of FollowPath when parenting to path (Normal parent still an option) Backward compatibility stuff to convert the per object axis settings to per constraint when a Track constraint is present. Function to convert old track to constraint (commented out) Revamped the constraints interface with Matt's work from tuhopuu and the stuff we were discussing earlier. -------------------- For coders: unique_constraint_name and *new_constraint_data moved to the kernel (constraint.c) new Projf function in arithb gives the projection of a vector on another vector add_new_constraint now takes a constraint type (int) parameter add_constraint_to_object(bConstraint *con, Object *ob) to link a constraint to an object add_constraint_to_client(bConstraint *con) to link constraint to current client (object or bone) add_influence_key_to_constraint (bConstraint *con) to (eventually) add a keyframe to the influence IPO of a constraint
