This helps to improve the accuracy of UV unwrapping and laplacian deform for
high poly meshes, which could get warped quite badly. It's not much slower,
doubles are pretty fast on modern CPUs, but it does double memory usage. This
seems acceptable as otherwise high poly meshes would not work correctly anyway.
Fixes T39004.

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):

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.
