Eevee: Fix Planar Reflection bug / background artifact.

This was cause by a missing uniform.

GPUTexture: Change default comparison mode to GL_NONE.

This default will prevent more errors in the future.
Also compare mode is less used nowadays.

Fixes T51904

Eevee: Fix the NaN pixel issue.

It's cause by degenerate triangle having normals set to (0,0,0) which may not be compressed like it should.
This fix the problem in the final indirect lighting evaluation which might be costly.

Add option to OpenImage operator not to detect sequences.

Otherwise, there would be no way to load a bunch of pictures with
'sequence pattern' in name in a single operation.

Related to T51778.

Eevee: Unlock compatible bsdfs in node add menu.

Eevee: Add support for common BSDFs.

Add Diffuse BSDF, and Glossy.

Also Use World normal instead of view normal as input.

Fix T51943: Depsgraph: world update happening eternally on background (set) scene

The issue was caused by updates being flushed for all scenes, while actual update
was only called for an active one.

Not sure why do we need to flush updates for all scenes, so now we only flush
scenes which are updated.

Merge branch 'master' into blender2.8

Fix T51955: Changing Auto-IK length crashes Blender (with new-depsgraph)

New dependency graph is tacking root bone into account when building the graph.
This is required in order to get proper dependencies between bones. so we can
reliably use bones as targets from the same rig (and even indirect relations
via external objects). This forces us to tag relations for update when we change
root IK chain bone.

Since relations rebuild is not fully trivial operation, we only do it for
the new dependency graph. In the future it'll be nice to avoid whole graph
rebuild for such cases, but that's mentioned as a TODO.

Fix T51015: Pack all into blend automatically leaves checkbox enabled.

Makes absolutely no sense to forcefully enable that automatic packing option here,
user can do this himself if they likes, from the very same menu...

Cycles: Add artificial memory limit debug option for OpenCL

Revert "Cycles: use std::min and max for extra overloads"

We already have this in util_algorithm.h

This reverts commit cff172c7621d89773baa99a9460f19056efb5f1e.

Cycles: Dont allow global size to fall to zero

Cycles: Detect out of memory before buffer allocation in OpenCL devices

Cycles: use std::min and max for extra overloads

Eevee: Volumetrics: Avoid light leaking if last step is going trough geometry.

Merge branch 'master' into blender2.8

Better fix for sequencer crash when text strip doesn't have effect data.

This situation happens when a file with a text effect sequencer strip is
loaded in Blender < 2.76 and saved. This destroys the effect data, causing
a crash in Blender ? 2.76.

d2f748a222ad19f prevented the crash when opening such a file, but accessing
the strip still caused a crash. This commit fixes that by actually
initialising the invalid strip. Of course this still causes data loss, but
that already happened by opening & overwriting the file in Blender < 2.76.

Eevee: Volumetrics: Fix enum flag.

Cycles: Fix compilation error after recent logging changes

This file uses std::ostream for helper << operators, so need to make sure
corresponding header is included.
