Fix rigid body not resimulating after cache invalidation

Fix 9cd6b03187b91bb2c267a45eac3cee7738e0e220 introduced a bug that
prevented simulation after a cache invalidation (for instance when
changing a setting after simulating). This fixes that.

Merge branch 'master' into soc-2017-normal-tools

Fixed all clnors in lnorspace not updating

Eevee: Add support for volumetrics in node tree.

Only volume scatter is implemented for now.

GPU Codegen: Add new closure socket type.

This allow specialized shaders to redefine the closure interface to fit their needs.

For instance, Volumetric closure needs to pass more than one vec4 (absorption vec3, scattering vec3, anisotropy float).

Eevee: Initial implementation of Volumetrics.

Draw Manager: Add new blend mode for transmission.

This blend Mode is doing Source + Destination * Alpha.

Eevee: Fix luma calculation for lamp fresnel.

Fix edit mode not drawing

This was introduced on 1ad0cc6bde.

Topograb: Update 3

Fix alembic after merge from master

Fix building with gcc6 after merge from master

Cleanup: Remove unused variables

WIP: Add volumetric while drawing

Merge branch 'master' into fluid-mantaflow

UI fix: disable snd parts threshold field when cache is baked

Cleanup: Remove unused line

WIP: Add geometry shader for volumetrics

Fix for merged 'normal map tangents not working correctly when there are no UV maps.'
