Fix for wrong capitalization in #include.

Updates to opennl for mesh laplacian matrix building, to make matrix
building with random access work together with variable locking.

Bone Heat Weighting
===================

This is a new automatic vertex weighting method, next to the existing
envelope based method. The details are here:

http://www.blender.org/development/current-projects/changes-since-244/skinning/

This is based on section 4 of the paper:

"Automatic Rigging and Animation of 3D Characters"
Ilya Baran and Jovan Popovic, SIGGRAPH 2007

Implementation Notes:

- Generic code for making mesh laplacian matrices has been added, which
is only used by bone heat weighting at the moment.
- Bone to vertex visibility checking is done with the raytracing code.
- Fixed an issue in the subsurf limit calculation function, where the
position of vertices on boundary edges was wrong. It is still not the
correct position, but at least it's in the neighbourhood now.

== Constraints - Important Bugfix ==

At last, the 'Local' option for Armatures works properly!
Tonight I went through carefully and cross-checked the code once again, and found several bad mistakes I had made. These were:
* the value of one variable from the armatures code was not what I expected it to be, based off the name).
* Mat4MulSerie swaps the first two args! Grrr...

Note:
There's only one rig that I've tested that was broken. That was slikdigit's "mancandy", and the part in question was the jaw. It is likely that a few more rigs out there (in particular, their 'local' action constraints) relied on the wacky rotation values that used to be used, so are now broken.

Draw.py - typo
sceneSequence.h - bad type check, dosnt matter really since that define isnt used yet.
SurfNurb.c - was using lib hashing function and surfNurbs not a lib! (own mistake)
buttons_editing.c - Curves PathLen button was MAXFRAMEF and pathlen is a short so the button wrapped around.

A few little code cleanups for constraints code. I've just removed some lines that weren't needed.

Previous bugfix for shadows cast on objects with diffuse reflectivity set to 0
caused errors on only shadow lamps; fixed this by adding back in the original
intensity > 0.0 check in the only shadow if statement, where it belonged in the
first place.

In addition, the specular pass was not correctly affected by only shadow lamps,
severely reducing the usefulness of this feature. For example, using four
spotlamps to create an omnidirectional buffered shadow lamp didn't work.

Remove spurious ";" in declaration, which causes warning in gcc and MSVC. Thanks Levi for catching this.

Small optimalization of drawing bones (drawsolidcube_size and drawcube_size) uses OpenGL displaylists.

missing include and added a warning to UIBlock

=Draw Module Fixed=

This commit fixes the Draw module. All buttons/widgets created via the Draw
module in a SpaceScript area are now inserted into a global list attached to
the SpaceScript data. This list is cleared before each draw, when freeing
the space, and when the area is switched to another space.c

This is necessary to prevent Blender's internal UI code from getting invalid
pointers to python data. In addition, it allows storing widget tooltips
inside the python Button objects, which solves that little bit of stupidity.

Note that this reverts the previous weaklist solution. In fact, I had to go
over each previous commit by Campbell after this code originally branched
before the weaklist commit and re-add each commit. So if anything is
missing, just tell me, or feel free to re-add it.

Object Transform:

If object has a parent, and constraints should not be inversed for transform, then constraints are now disabled like tracking is.

fix from 2.44 for adding new curves.

Refactor the raytracing code to split the tracing and shading parts into
two separate files, raytrace.c and rayshade.c. The tracing code can now
be used separately from the renderer (will be used in a later commit),
and the raytracing acceleration structure can now also be easily replaced,
if someone wants to experiment with that.

== PyAPI - Constraints Space Conversion Access ==

Now, for the constraints that support Constraint Space Conversion, those settings can now be set from the PyAPI too.

PyAPI Simple Bugfix:

This fixes a bug reported in IRC. getParentBoneName() was returning a string (most likely from an old bone-parent that got removed), even when the parent wasn't an Armature.

Transform - Objects with Old-Tracking:

Tracking is now tempolarily disabled while an object matrix used for space conversions stuff is calculated. This used to be done before the constraints recode.

removing unneeded checks

Cleaned up some case issues with language files...

Transform Bugfixes Part 2 (Constraints Related):

Now PoseBones should transform normally again with constraints applied and in other cases. I've gone back to the old code that used to be there before the recode, and added the constraint inverse (as appropriate) into that.
