Blender Git Loki

I restricted some keyboard events.
I wrote a descriptive message of support in the area of the screen.

Test files were removed.
I remove the computation of implicit rotations because not improve the solution.
I eliminate the use of the library Eigen3 in my system because SuperLU library has better performance.

Testing deformation without compute implicit rotations.
Implicit rotations cause erroneous solutions.

svn merge ^/trunk/blender 58040:58270

The code was organized and optimized.
The system has problems with the handling of events.
The deformation system is activated with the special menu key W "Laplacian Deform" in vertex editing mode.
The system works with keys Pkey, Hkey, Skey
You must mark the static vertices with Skey, then the handlers with hkey, and then you can move the handles and calculate the deformation with Pkey.

Mesh Sketch based on Laplacian Deform implemented as EditMesh tool.
