a28e014313 BMesh: Add API call BM_face_calc_point_in_face 
Was local to knife code, but this is generally useful.

d28431a648 OpenNL: make the API thread safe by always passing context. 
Previously two laplacian smooth or deform modifiers executing
simultaneously could crash.

d47fbece51 BMesh: improve face-path-picking w/ tri-fans 
Face paths including triangle-fans would often be avoided because
the face center and edge would 'zig-zag'.

Resolve using wighted face center and picking an edge-point between face centers.

410ca0ed92 Recent change to bmesh_jekv caused assert 
Note that the mesh was valid, this just stops the radial check from failing.

29d9140fce Fix T46804: Crash using triangulate modifier on a specific mesh. 
Issues was again the ugly hack of swapping last generated tri with original face
we use in BMesh triangulate code - here it could lead in some rare case to have
invalid face pointer in doubles list.

8bdb884289 Fix related to T46804 - BMesh validate code would use invalid pointers after checking them! 
Note that this does not fix the issue reported in T46804, juts makes it crash later down in code...

a3530b35bd Fix T46784: Connect vertices (follow up) 
Another fix for a slightly different case from the original report, to give better orientation.

Vertex normals influence on the orientation is now scaled by the alignment with the cut direction.

Also use face normal instead of loop normal which can be unreliable when the corners edges are co-linear.

3863660c37 Fix face creation using incorrect loop-custom-data 
Custom-data on newly created face data was often rotated.

Now the API doesn't copy data from adjacent loops when creating faces.
Most functions were already overwriting this anyway.

Since such decisions are better made at a higher level, now it's the responsibility of the caller.

56bcda8bc6 Fix BMesh selection flushing w/ mixed modes 
Fix for T46494 wasn't working properly when de-selecting faces,
adjacent faces would remain selected but have unselected edges.

Logic here is admittedly rather fragile since it relies on both
selection functions and flushing afterwards.

92ab3ba385 Fix T46648: Recalculate normals fails 
Certain shapes could trick the inside/outside test.
An edge between 2 planar faces could be selected for detecting face-flipping (which failed).
While this could be prevented by skipping those edges,
use a method which searches for the outer most face-loop, then check it faces the center.

123b64f818 BMesh: improved smooth subdivision 
Instead of offsetting along normals, smooth positions are now
calculated on a sphere defined by the vertices and their normals.

This removes visible seams along original edges, which were common previously.
