Fix T51434: Module math operation is wrong in GLSL shading

Based on patch from @lazydodo.

Reviewers: sergey

Differential Revision: https://developer.blender.org/D2661

Cycles: Enable BPT for NVidia OpenCL

Fix assert failure caused by bug in sequencer interface script

If icon_only is True then one must not pass text attribute.

Libmv: Fix strict compiler warnings, unused variables

Fix T51439: Object not updated when particle system settings change in 2.8

A bit too early to disable workaround for particles.

Guess it was commented out after particles removal but was not brought back
after particles restore commit.

UI: Editor menu, move VSE below MCE

The idea here is to keep things in a logical order to match the order of ones worflow.
This concept can be seen in Graph > Dope Sheet > NLA. This issue is mainly affecting the manual.

Fixes T50709

DWM: share positions & normals in shading VBO.

Cleanup: rename layer-names -> layer-uuid

These names are created from a hash,
don't confuse with actual layer names.

DWM: Tangent support for editmesh

Fix missing render update when building without OCIO but having GLSL image draw method

Fix crash and assert failure when using OCIO GLSL draw mode and color management disabled

The issue was happening when display device is set to None, which makes it so
all the color transformation is a no-op which does not really require any LUT.

This is something we can not know from Blender side easily, because LUT sampling
and related logic is fully done in OCIO library itself. The following happens:

- OCIO sees that no LUT is needed and uses simple pass-through logic in the
color conversion function.

- GLSL compiles sees that uniform used for LUT is unused in the GLSL code and
strips it out.

We can not know this from Blender side because technically any conversion to
the same space might be a no-op and that we wouldn't know without some tricky
parse of the OCIO configuration.

So for now we simply avoid crash but are disabling checks for existence of the
uniform.

Ideally would be nice to have some GLSL-code parses which gets the uniforms
from the code itself, so we can distinguish between typo in the uniform name
and uniform being optimized out.
