== SDNA - Code Comments ==

Added a few comments about various Animation-System Related structs. Hopefully, these will be helpful for people trying to get familiar with the code.

added commends to some DNA_*.h files - as well as some TODO's for removal.
header_view3d.c was doign an implicit declaration also.

commiting ettore fourth patch (plugin path)

=Shapekey Missing Undopush bugfix=

Added some missing undo pushes in editkey.c. Now when you add/delete
shapekeys, you can do undo and actually have it undo adding/deleting the
shade keys.

== Constraints Work - PyAPI ==

A few tweaks to documentation and implementation of PyAPI access for constraints following Constraints recode. Just doing a little bit of cleanup.

Removed a variable that wasn't needed, but somehow ended up in the commit the other day.

Small fix: need set the color before call glRasterPos or don't work.

Bugfix #6831: Crash when combining duplivert and mirror

I've added checks which should prevent crashes in this case. Sometimes vertex_dupli__mapFunc is called with no_f being NULL, but no_s should not be NULL in those cases.

updated scons build system, neccesary after erwin's commit

bugfixes for generic (experimental) Bullet rigidbody constraint: use cone-twist instead (needs a few more minor fixes)

Note: Visual Studio projectfiles and other buildsystems need to add extern/bullet2/src/BulletDynamics/ConstraintSolver/btConeTwistConstraint.cpp to the project!

Bugfix #6945: Weight painting bug

Trying to Clear Rotation of a armature bone while in Weight Painting mode didn't work anymore due to Bugfix #6486. Now it checks if ob==active_object and also if weightpainting is on.

was missing colorband from the flags in the epy docs

== MSVC 7.1 project files ==
- updated bullet files with btConeTwistConstraint.h and btConeTwistConstraint.cpp

== MSVC compilation ==
two small fixes in this commit:
- added new file for nodes
- fixed compile error in readfile.c, as reported by Jean-Michel Soler here:
http://lists.blender.org/pipermail/bf-committers/2007-July/018849.html

commiting fixes from Ettore for building on linux & win 32

A few minor changes:

* Removed obsolete comments from constraints code
* ChildOf constraint buttons: Set/Clear Inverse are now Set/Clear Offset. Hopefully that makes it a bit clearer for users.

Bugfix #6915:

Passepartout function hides camera name (show name).
Now it uses the Text-Highlighted theme colour instead.

== TrackTo Constraint ==

Now this constraint has the space-conversion buttons too (by special request of joeedh).

== Constraints System ==

After just over a week of coding, I've finished doing a major refactor/cleanup of the constraints code. In the process, quite a few old kludges and ugly hacks have been removed. Also, some new features which will greatly benefit riggers have been implemented.

=== What's New ===
* The long-awaited ``ChildOf Constraint'':
This allows you to animate parent influences, and choose which transformation channels the parent affects the child on (i.e. no translation/rotation/scaling). It should be noted that disabling some combinations may not totally work as expected. Also, the 'Set Inverse' and 'Clear Inverse' buttons at the bottom of this constraint's panel set/clear the inverse correction for the parent's effects. Use these to make the owner not stick/be glued to the parent.
* Constraint/Target Evaluation Spaces:
In some constraints, there are now 1-2 combo boxes at the bottom of their panel, which allows you to pick which `co-ordinate space' they are evaluated in. This is much more flexible than the old 'local' options for bones only were.
* Action Constraint - Loc/Rot/Size Inputs
The Action Constraint can finally use the target's location/rotation/scaling transforms as input, to control the owner of the constraint. This should work much more reliably than it used to. The target evaluation should now also be more accurate due to the new space conversion stuff.
* Transform - No longer in Crazy Space (TM)
Transforming objects/bones with constraints applied should no longer occur in Crazy Space. They are now correctly inverse-corrected. This also applies to old-style object tracking.

=== General Code Changes ===
* solve_constraints is now in constraints.c. I've removed the old `blend consecutive constraints of same type' junk, which made the code more complex than it needed to be.
* evaluate_constraint is now only passed the constraint, and two matrices. A few unused variables have been removed from here.
* A tempolary struct, bConstraintOb, is now passed to solve_constraints instead of relying on an ugly, static workobject in some cases. This works much better.
* Made the formatting of constraint code consistent
* There's a version patch for older files so that constraint settings are correctly converted to the new system. This is currently done for MajorVersion <= 244, and SubVersion < 3. I've bumped up the subversion to 3 for this purpose. However, with the imminent 2.45 release, this may need to be adjusted accordingly.
* LocEulSizeToMat4 and LocQuatSizeToMat4 now work in the order Size, Rot, Location. I've also added a few other math functions.
* Mat4BlendMat4 is now in arithb. I've modified it's method slightly, to use other arithb functions, instead of its crazy blending scheme.
* Moved some of the RigidBodyJoint constraint's code out of blenkernel, and into src. It shouldn't be setting its target in its data initialisation function based + accessing scene stuff where it was doing so.

=== Future Work ===
* Geometry to act as targets for constraints. A space has been reserved for this already.
* Tidy up UI buttons of constraints

Python API
----------
Remove unused variable declaration which caused gcc warnings.
