Implementation based in part off the paper "B-Mesh: A Fast Modeling
System for Base Meshes of 3D Articulated Shapes" (Zhongping Ji,
Ligang Liu, Yigang Wang)
Note that to avoid confusion with Blender's BMesh data structure,
this tool is renamed as the Skin modifier.
The B-Mesh paper is current available here:
http://www.math.zju.edu.cn/ligangliu/CAGD/Projects/BMesh/
The main missing features in this code compared to the paper are:
* No mesh evolution. The paper suggests iteratively subsurfing the
skin output and adapting the output to better conform with the
spheres of influence surrounding each vertex.
* No mesh fairing. The paper suggests re-aligning output edges to
follow principal mesh curvatures.
* No auxiliary balls. These would serve to influence mesh
evolution, which as noted above is not implemented.
The code also adds some features not present in the paper:
* Loops in the input edge graph.
* Concave surfaces around branch nodes. The paper does not discuss
how to handle non-convex regions; this code adds a number of
cleanup operations to handle many (though not all) of these
cases.
The remesh modifier doesn't currently get any data from original
faces, so even if the input mesh was entirely smooth none of the
output faces would be. Solved by adding a new
dna-flag/rna-bool/UI-checkbox to smooth shade the output.
Requested by Daniel Salazar.
* Fix an alignment issue, column_flow layout apparently does not use the whole width, leaving a small gap on the right side. This should be fixed in the layout engine, but too close to release now.
* This patch adds a influence slider for the lattice modifier, which affects the strength of the deformation.
Patch by Patrick Boelens (senshi), thanks a lot!
this is no big improvement but at least its not a regression.
using the new operator for the bevel modifier can be enabled again be uncommenting a define.
* Hide Modifier and Contraint Panel header, this gives a bit space.
As it's the only panel in these context tabs it does not make sense to close them anyways.
* Some tweaks to the modifier UI
* Hide sharpness property, instead of greying out.
The policy is to use greying out when a property depends on a boolean, if it depends on an enum item, hide it.
* even offset, uses same shell distance method as solidify to give even with beveled faces.
* distance offset, this is mostly for compatibility with the modifier in trunk which uses the bevel width as a distance rather then a percentage. at the moment this is awkward for the operator since it makes percent act differently where the 0-1 range doesnt make sense.
still need to bring back more options from trunks bevel modifier.

Rationale: the name was confusing and not always used consistently, and this
map itself is not something that can be layered, rather the map can be used
as texture coordinates in some layered setup.
The original intent was to indicate this contained more than just UV's, but
the game engine settings have already been moved out, and apparently users
didn't really get this from the name anyway.
* Changed the user interface for the Ocean modifier, to use less space and look better.
* Changed rna name cachepath to filepath for consistency (fluid cache path also uses "filepath")
