Merge branch 'master' into newboolean

Merge branch 'master' into newboolean

Fix wrong use of initializer in C++. Fix unused parameter.

Fix a coplanar case - two cubes forming steps.

Needed careful logic about what to do with zero volume cells.
It worked before on some cases by accident, but now it should
work on any depth stack of coincident faces.

Use floating point filtering to make the degenerate triangle detection faster.

Set up to try either spinlock or mutex for boolean parallelism.

On my 48 core Linux machine, mutex's seem to lead to faster execution.

Use multithreading to calculate subdivided triangles.

Merge branch 'master' into newboolean

Used wrong #if to isolate debugging code for Windows.

Fix the knife boolean modes.

Had to track the intersect edges through from mesh_intersect
through to the bmesh boolean.

Turn off debug file writing in boolean etc unit tests.

Also, for Windows, do something other than /tmp when file writing
is turned on. This file writing is only intended for debugging.

Interpolate face loop data from example faces.

This makes for a reasonable first pass at getting OK UV maps.

Use original edges as examples when possible.

These means that, for example, an original edge that has a bevel
weight and only survives partly after the boolean will still
have that bevel weight.

BMesh construction now better at preserving attributes of mesh elements.

Uses existing BMVerts, BMEdges, and BMFaces if possible.
Uses good examples for BMFaces for intersected faces.
Still todo: good examples for BMEdges when partially reusing an edge,
and UV interpolation for new faces.

Merge branch 'master' into newboolean

Fixed the regression after making binary ops not do self-intersection.

Now the new Boolean code is only about 3 to 4 times slower than the
current BMesh one.

Merge branch 'master' into newboolean

Update integer type usage

Merge branch 'master' into newboolean

Work in progress to treat nary boolean differently.

This will make it faster. There's one bug in it still,
but committing progress.
