Static Override: Lock 'edition' of constraints & modifiers from overridden data.

Means that you cannot move or delete constraints/modifiers coming from
the overriden linked datablock. Local inserted ones can be fully edited.

Paint Vertex Mode: Fix shader not free.

Eevee: Add Lamp Specular multiplier.

It's usefull in some scenario to tweak the specular intensity of a light
without modifying the diffuse contribution.

Cycles allows it via lamps material which we currently not support in Eevee.

This is a good workaround for now.

Fix T54864: Assert when changing interface display scale

The asserts were introduced on rB5f6c45498c92 (top-bar).

Although the asserts are technically correct, they would fail even in master.
And the commit simply added the asserts without fixing the situation itself
(as you can see in the report, it is really simple to reproduce this issue).

I propose we remove the asserts and bring them back only when the situation
itself is fixed. It doesn't make sense to introduce asserts that would fail
with the current state of the code.

Static Override: add insertion for modifiers and one constraints, fix editing of inserted items in collections.

Now insertable collection items have a flag to say they are 'local' (and
hence can be freely edited).

Merge branch 'blender2.8' of git.blender.org:blender into blender2.8

Workbench: Linear => srgb conversion

Fix mysterious crash on tooltips

This was a hard to reproduce bug, but it happens often enough.
Basically the tooltip of the active tool was been invoked when
context had no valid ScrArea which would lead to a crash.

We now just return no tooltip in these cases.

Depsgraph: Add function to iterate over all original IDs

Use meaningful debug name for render depsgraph

Depsgraph: Show log message when tagging specific depsgraph ID

Depsgraph: Add per-depsgraph debug name which is shown in the logs

This way we can see for which depsgraph datablock is being evaluated for.

Depsgraph: Cleanup, naming conventions

Depsgraph: Make all print messages to respect per-depsgraph debug flags

Depsgraph: Allow per-depsgraph debug flags

Currently only affects EVALUATION debug messages, rest are to be
supported on per-depsgraph level.

Depsgraph: Use utility function to print CoW update function

Depsgraph: Make bAction a part of dependency graph

There are various values which depends on context in there, for example
current driver value and original DNA value f-curve is applied for.

This partially fixes issue with not being able to tweak keyed values
when material preview is open.

The material preview is not being currently updated against non-keyed
changes since every tweak of material property does full preview scene
depsgraph evaluation.

Workbench: Fix interface change in draw maanger

Merge branch 'blender2.8' of git.blender.org:blender into blender2.8

Vertex Paint: Use Linear colors for interpolation.

This matches Cycles and Eevee's behaviour.
