/* Function prototypes */
Constraint stuff from tuhopuu including (but probably not limited too): 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

Armature related fixes and cleanups: * Armatures that had constraint targets inside other armatures weren't transform()-ing correctly * Issues with lattice deformed objects that are parents of bones when rendering an animation. Seems to be mostly OK now with the exception of the first rendered frame -- weird bugs like this have plagued blender for ages, which leads me to believe that RE_rotateBlenderScene() is a piece of garbage that nobody understands (especially me). * made a few helper functions to clean up some repeated code related to clearing constraint status and rebuilding displists.

void do_constraint_channels (struct ListBase *conbase, struct ListBase *chanbase, float ctime);
Renamed get_constraint_target in constraint kernel file to get_constraint_target_matrix since that's what it really does Moved get_con_target from editconstraint to constraint kernel file and renamed to get_constraint_target Make scene.c use constraint functions from kernel instead of doing the switch itself (regrouping specific constraint code in one file). Add LockTrack as an option in the Make Track menu (Ctrl-T) Adding fun for vortex forces in 3D window, the representation now match the orientation and direction of the force (this is code will need optimisation). I'll probably be slapped for mixing two things in one commit but some function calls needed to be fixed for the new spelling and since this is really isolated code I didn't feel like wasting time getting a fresh copy, doing the changes and then readded this after commiting. Fixed some warning regarding implicit casts and constants (this last one is a MSVCism where you need to explicitely tell the compiler to use floats with an f. AFAIK, it doesn't affect/bother other compilers). Removed a useless commented piece of code in readfile (there was an uncommented copy a couple of lines before)

/* Gemeric functions */
No line for constraint without target Code notes: The constraint_has_target can be used to test if a constraint has a target at all.

fixed spacing in the headers to get rid of some warnings and some other little minor spacing issues.
