Shading: Add more operators to Vector Math node.

Add Multiply, Divide, Project, Reflect, Distance, Length, Scale, Snap,
Floor, Ceil, Modulo, Fraction, Absolute, Minimum, and Maximum operators
to the Vector Math node. The Value output has been removed from operators
whose output is a vector, and the other way around. All of those removals
has been handled properly in versioning code.

The patch doesn't include tests for the new operators. Tests will be added
in a later patch.

Cleanup: remove old Windows scons installer, this is handled by CMake now

Cleanup: Fix build error with MSVC

Previously eigens internal include order somehow implicitly provided
M_PI and friends. The recent eigen version bump broke this implicit
behaviour, better to be explicit that we need the math defines for MSVC.

improve const correctness in many places

Merge branch 'master' into functions

Timeline: refactor cache drawing

I did this mostly to get to know the point cache from this direction.
This should not change anything from the user perspective.

LibOverride: Fix inverted logic in RNA collection operation application.

Note to self: need to recheck the namings of whole override code,
currently this is way to confusing and inconsistent.

Cleanup: minor error in assert message in libOverride collection code.

Modify .gitmodules to use Tangent Anim subrepo for addons

Modified release/scripts/addons to point to git://github.com/tangent-animation/blender-addons.git, branch blender-v2.80-release

Merge from master.

Mask filter: update only modified nodes

Fix T68826 Eevee: Multi-Mat not working if switching from Solid shading

The correct fix would be to avoid all those hacks but this is needed if
we want to be able to parallelize object vbo extractions.

OpenVDB: Fixed in-memory rendering.

GPU: Fix Element index range calculation

Fix T68880 2D line display is broken

Fix raw allocator

This allocator is necessary because sometimes we don't want to use
Blenders guarded allocator. Especially when an object lives longer
than the guarded allocator.

Update Eigen to 3.3.7

This is in preparation for the QuadriFlow remesher lib.
