Added LSCM UV Unwrapping:

http://www.loria.fr/~levy/Papers/2002/s2002_lscm.pdf

Implementation Least Squares Conformal Maps parameterization, based on
chapter 2 of:
Bruno Levy, Sylvain Petitjean, Nicolas Ray, Jerome Maillot. Least Squares
Conformal Maps for Automatic Texture Atlas Generation. In Siggraph 2002,
July 2002.

Seams: Stored as a flag (ME_SEAM) in the new MEdge struct, these seams define
where a mesh will be cut when executing LSCM unwrapping. Seams can be marked
and cleared in Edit Mode. Ctrl+EKEY will pop up a menu allowing to Clear or Mark
the selected edges as seams.

Select Linked in Face Select Mode now only selects linked faces if no seams
separate them. So if seams are defined, this will now select the 'face group'
defined by the seams. Hotkey is still LKEY.

LSCM Unwrap: unwrap UV's by calculating a conformal mapping (preserving local
angles). Based on seams, the selected faces will be 'cut'. If multiple
'face groups' are selected, they will be unwrapped separately and packed in
the image rectangle in the UV Editor. Packing uses a simple and fast
algorithm, only designed to avoid having overlapping faces.

LSCM can be found in the Unwrap menu (UKEY), and the UV Calculation panel.

Pinning: UV's can be pinned in the UV Editor. When LSCM Unwrap is then
executed, these UV's will stay in place, allowing to tweak the solution.
PKEY and ALT+PKEY will respectively pin and unpin selected UV's.

Face Select Mode Drawing Changes:
- Draw Seams option to enable disable drawing of seams
- Draw Faces option to enable drawing of selected faces in transparent purple
- Draw Hidden Edges option to enable drawing of edges of hidden faces
- Draw Edges option to enable drawing of edges of visible faces

The colors for these seams, faces and edges are themeable.

Added SuperLU 3.0:
http://crd.lbl.gov/~xiaoye/SuperLU/

This is a library to solve sparse matrix systems (type A*x=B). It is able
to solve large systems very FAST. Only the necessary parts of the library
are included to limit file size and compilation time. This means the example
files, fortran interface, test files, matlab interface, cblas library,
complex number part and build system have been left out. All (gcc) warnings
have been fixed too.

This library will be used for LSCM UV unwrapping. With this library, LSCM
unwrapping can be calculated in a split second, making the unwrapping proces
much more interactive.

Added OpenNL (Open Numerical Libary):
http://www.loria.fr/~levy/OpenNL/

OpenNL is a library to easily construct and solve sparse linear systems. We
use a stripped down version, as an interface to SuperLU.

This library was kindly given to use by Bruno Levy.

Ack! Fixed something without testing... this broke updates for numbuts
in picker.

This commit add the clock wipe effect to the sweep menu in the sequence editor

added support for ortho camera (needs yafray from cvs)
When using xml export, yafray will now render the alpha channel as well when 'RGBA' button in blender is enabled (Plugin does this automatically).
In plugin code, fixed smooth shading bug for non-mesh objects.
Relative paths for textures are now recognized (plugin & xml).
Fixed problem with duplicate objects (plugin & xml).
Really old bug, sun position is now correct (plugin & xml).
World background now can also be a regular image texture (jpeg & tga), but for now always assumes spheremapping, which is not the same as Blender either. In yafray the texture is assumed to be a full 360 (panorama type) map.
convertBlenderScene.c cleanup, the identity transform 'hack' is removed.
THIS AFFECTS ALL EXTERNAL RENDERERS (Aqsis and others) WHICH RELY ON THE RENDERDATA OUTPUT, VERTICES AND LAMPCOORDINATES/VECTORS NOW NEED TO BE TRANSFORMED BACK TO WORLD COORDINATES. See yafray plugin/export code.

- changed sequence for finding HOME on Win32. Sequence is now as
shown at http://www.blender3d.org/cms/Installation_Policy.352.0.html

Still TODO: update NSIS installer script to suit the change.

* Fixed action conflict (win32):
When also enabling the blenderplayer there would be a action conflict for the resource building.

- Simple optimizing for deflected (collision) particles. It now caches
transformation (from vertex -> world space), used defines for vecadd and
vecsub, and intersects quads more efficient.
Result is about 2 times faster.

- Added draw mode for empty used as forcefield

- added defines VECADD and VECSUB

Tiny cleanup in call for glBitmap. Don't see any error in using it for
drawing vertices... on OSX this works 100%, also in zbuffer mode and with
transparent faces.
Code is simple enough for a linuxer to further test!

Some tiny dialog message cleaning for easier scan-reading.

Forgot to include glutil.h

Long on the todolist: a patch to have pointsize working on systems that
don't have them larger than 1, since vertices are drawn with it.

It is solved by patching code with minimal confusement. So you can get
automatic patched glPoints with:

bglBegin(GL_POINTS);
bglVertex3fv(vector);
bglEnd();

In glutil.c the wrapper can be found, that checks for maximum Pointsize,
and bypasses it to a glBitmap then.

Added B_NOP to events buttons on wipe type effects panel.

Small improvement in detecting which previews need update in Blender.
Now you can have multiple buttons windows open, for example one showing
only a larger material preview, and have it updated correctly. Nice for
setups where you can keep preview shown while scrolling buttons.

Added colorpicker in Panel for:

- Transform properties 3d win, while Vertex/Texture paint is on
- Paint panel in UV window

Note; both use the same GVP struct to store current color in. Also the
function used now to add picker isn't complete... might need further
thinking over. Consult me when you like them in more places.

More closely implement the Installation Policy
<http://www.blender3d.org/cms/Installation_Policy.352.0.html>

- Within those confines 'ERROR: File ".Blanguages" not found' won't show up
again (all such bugs in tracker have already been closed, #745 for reference)

And intrr, if it does, 'cp -a .blender ~' already :P


Of course, this issue should not be fixed on a per file basis (.Blanguages,
.bfont.ttf), but instead return the .blender dir location. Duplicating .blender
finding logic everywhere, sigh.

< jesterKinky> that's what I meant. for now this is ok to continue with, and then in a later stage correct it all in one bigger effort
< jesterKinky> and since you point code at policy url we all can get reminded of how it was supposed to go when cleaning it.
< LarstiQ> jesterKinky: yes, I meant to do a "grrrr, this is the last time I'm not fixing the underlying issue"
< LarstiQ> all your lazy coders are belong to me
< jesterKinky> set us up the superficial bugfix

Added edges in Mesh undo.
Note; whether or not edges are created is derived from original Mesh, the
one still residing in obedit->data while modeling.

Changed weird line in add_primitiveMesh() that caused cursor to flip back
to normal mousepointer while in editmode.
Was in code since 2.25...

Made effector strenght as big in the negative as in the positive.

Compressed the two particles effectors loop into one. It was rather stupid of me to do it as two at first, but it was the first thing that came to mind. Fixed now, so it will calculate much faster.
