Surface Deform Modifier (SDef)

Implementation of the SDef modifier, which allows meshes to be bound by
surface, thus allowing things such as cloth simulation proxies.

Fix memory leak when making duplicates real and parent had constraints

Thanks Bastien for help!

Clay Engine: Edit Mesh overlay fix jaggy edges.

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).

Fix changing device activates it unintentionally

Activating in this context means that OpenHMD starts polling the device
for rotation values. That can slow down things, so we only do it when
actually starting an HMD session.

Don't check if HMD returns valid IPD

OpenHMD always returns a valid value, so this check is just a waste of
resources.

Use solid draw mode by default for HMD view

Fix/workaround T50677: Shrinkwrap constraint don't get updated when target mesh gets modified

Do a "full" update on leaving sculpt mode, so we are sure scene will be brought
to a consistent state.

Ideally we'll only do that when there are objects which depends on geometry
without re-calculating self geometry, but that's a bit tricky currently.

Fix wrong modelview matrices

Was wrongly applying modelview matrices from HMD onto Blender's.

Similar to previous commit, but for object constraints

Depsgraph: Shrinkwrap constraint actually depends on geometry

Cycles: Fix compilation error on vanilla Ubuntu 16.10

Patch by @swerner, thanks!

Fix T50634: Hair Primitive as Triangles + Hair shader with a texture = crash

Attributes were not resized after pushing new triangles to the mesh.

Fix part of T50634: Hair Primitive as Triangles + Hair shader with a texture = crash

Wrong formula was used to calculate needed verts and tris to be reserved.

Cycles: Make it more clear values never changes by using const qualifier

Merge branch 'writefile_rework' into id_override_static.

That way we don't have to add the same stupid few lines to *all*
datatypes writers! Obvious gain on efficiency and security from coding PoV.
