Fix T60855: workspace duplicate does not preserve addons filters.

Fix T61906: crash rendering softbody with Cycles and timeline visible.

Make sure we don't reallocate arrays in the pointcache when not needed, the
size of a memory allocation can be slightly bigger than the requested size.

Also, use consistent check for shared cached in copy and free functions.

Cleanup: fix warning about unused parameter.

UI: Add brush controls to contextual menu in Weight Paint mode

Maniphest task: T62130

Fix T61053: crash baking to float image after file save.

This is the wrong flag to check, no other code actually reads it.

Fix T61103: Cycles bevel wrong on objects with negative scale.

Fix T61831: Denoising Clean pass not scaled correctly with samples.

View3D: Fix object without bounds displaying bounding boxes

View3D: Fix Empties displaying bounding boxes

Despgraph: Make dupli objects inherit the parent's display type

Fix T61152 Instanced Collections Don't Honor Viewport Display Setting

Tools: Add Selection tools to Texture Paint toolbar when Face Selection is enabled.

Consistent with the other paint modes.

Eevee: Update LTC code

Main change are:
- the fresnel LUT is separated from the main GGX LUT.
- LUTs use sqrt(1.0 - NV) as roughness remapping. Improving precision and
removes needs for acos().
- LTC LUT is normalized by matrix middle component. Improving precision.

Merge branch 'blender2.7'

Color management: Fix/workaround broken getDefaultDisplay()

This is something what is caused by OCIO library. The patch
has been submitted there:

https://github.com/imageworks/OpenColorIO/pull/638

For until it is refined and checked we do workaround from
our side.

Color management: Query default view from display

Solves weird situation when default display name is queried
from OCIO, but Default view being assumed to be set for it.

Now view is initialized to a default view of that display.

GPencil: Fix unreported problem with input samples

The parameter was not working because it ws testing for guides only.

GPencil: Cleanup comment text

GPencil: Fix unreported UV error when use subdivide modifier

When the subdivide modifier was used, the UV was not recalculated and the texture of the stroke was wrong.

Fix T62255: Blender defaults to "OpenAL Soft" in sound settings, regardless of saved preferences

- Default device (index 0) was hard coded.
- Also fixing crash with invalid device passed to blender via -setaudio.

Fix T62393: Materials made from 'Make Single User' have linked animation.

`id_single_user()` was still code from older ID management, now we can
use modern code to handle animdata duplication for us (which allows to
keep handling of nasty sub-data ID horrors like nodtrees in a single
place, much safer and simpler).
