ab2c273b12 Added GPL header to sconscripts!
Also changed shebang to '#!/usr/bin/env python', this is more portable across unixes...

e8bc62e162 Avoid unecessary minimizer calculations in dualcon
* The minimize() function, which solves a least-squares problem, is
  only needed for sharp remesh mode, but was being calculated for
  smooth and blocks modes as well. Disabling this calculation when
  it's not needed gives a big performance boost.

10d1cde0ad Potential fix for bug #31111, Remesh modifier generates artifacts on simple surfaces
Changed one of the intersection tests to use < rather than <=

The sharp and smooth modes look fine now for the special case that was
reported broken; blocks mode looks correct but "jumps" slightly from
one octree resolution to another, so may need additional corrections.

3d65c502e1 More code cleanup in intern/dualcon.
Removed a lot of unused code, added comments and some clearer
naming. Minor code shuffles and style cleanup too.

850636e0e4 Remesh modifier: extensive refactoring of the Octree class.
The changes mostly center around two new structures, InternalNode and
LeafNode. These provide an explicit representation of the Octree
nodes, which formerly were manipulated as opaque byte arrays.

A fair amount of commented out/unused code was also removed. This
includes the "CINDY" code, which may yet be useful, easy to bring back
if so.

There should be no difference in the output of the remesh modifier,
but memory usage may be slightly different. The flood fill bytes are
no longer optional; they will be allocated whether or not the 'remove
disconnect components' flag is set. The leaf node is probably not as
tightly packed due to alignment issues; this could be fixed with the
__attribute__((packed)) flag in gcc (probably there's an MSVC
equivalent), but not sure it's worth it. The internal nodes should
take up less space on 32-bit systems, allocating sizeof(pointer) now
rather than constant eight bytes.

These changes were made in persuit of bug #30158 (remesh crashes on
PowerPC). There's still a fair amount of bitwise stuff in the Octree,
so may still be endian issues and not yet sure if this fixes the bug,
but should be much easier to track down problems now.

2b7ca2304a unify include guard defines, __$FILENAME__
without the underscores these clogged up the namespace for autocompleation which was annoying.

289c8b5758 Add remesh modifier (dual contouring).
This patch adds a new remeshing modifier. The algorithm is based on
the paper "Dual Contouring of Hermite Data", and the implementation
was contributed to Blender by Dr. Tao Ju.

The contributed code is in intern/dualcon, and was modified to compile
under gcc and work on 64-bit systems. Files not needed for Blender
were removed and a small C wrapper was added in order to interface it
with Blender. The rest of the patch is just standard modifier stuff.

The remesh icon was contributed by Zafio:

Thanks to everyone in that thread for the icon proposals and
discussion.
