We do a strip of triangles around the triangle of interest and modify the variying vars to "trick" the fragment shader into rendering what we need.
This keeps the compatibility for both shaders.
Vertex still get half displayed when angle at the vertex is very acute.
This patch is only for the simple, no vert clipped case.
This is 2.5x slower than without the trick (on my hardware with 1million tris).
Based on the previous overlay shader from merwin.
This shader takes care of clipped vertex cases and do all edit mode face info in one pass (except face centers).
As the shading is done one the triangle itself the visual can't go beyond the surface of the mesh. That leads to half displayed edges on the outline of the mesh.
This problem can be fixed by a second pass.
This is work in progress.
Can't see any reason to call AUD exit early in WM_exit, that's a
low-level module that has no dependency on anything else in Blender, but
is dependency of some other parts of Blender, so it should rather be
exited late in the process!
This was causing blender to segfault.
We now add create a new collection and link to the layer before adding
the new object
(also included unittests, and requires updated lib/tests)
This adds an option to force fields of type "Force", which enables the
simulation of gravitational behavior (dist^-2 falloff).

Note that since there is no (efficient) ways to get arrays of
MVert/MEdge/etc. out of a BMesh, I refactored quite heavily internals of
BKE_mesh_render.
Now, when you do need acess to mesh data to generate cached batches, you
create an abstract struct from mesh (either Mesh or BMesh if available),
and then use advanced helpers to extract needed data, on a per-item
basis (no more handling of arrays of verts/edges/... in batches code).
This allows to:
* Avoid having to create arrays of BMesh elements.
* Take advantage of existing advanced BMesh topology and connectivity data.
