Fix T56180: Grease Pencil edit mode select menu crash.

Note that there are most certainly many other operators that?d need that
same flag... Don?t have time to hunt them down currently, will just fix
as issues are found, for now.

Fix T55791: blender 2.8 crash on redoing 'snap to cursor' with Offset option ON.

Many snap_to operators need a fully evaluated depsgraph to run
properly...

Operators: add a new flag stating that operator needs access to evaluated data.

For now, that flag is only used in redo code, since after undo step
depsgraph is totally empty... We *may* want to add at least an assert in
op calling code too, though?

Depsgraph: add helper to ensure a given scene/view_layer graph is up-to-date.

Since that call make the graph active, it should only be used in active
editing context aware code (i.e. essentially, operators).

DRW: Augment Debug messages

Eevee: Fix assert with hair drawing

This remove unused clip_block when not needed and the useless ubo bind that
were put there for the sake of not crashing.

Merge branch 'master' of git.blender.org:blender into cycles_texture_cache

# Conflicts:
# intern/cycles/render/image.cpp
# intern/cycles/render/nodes.cpp
# intern/cycles/render/osl.cpp

Icons: add particle brush icons

minor cleanup and fix memory leak (resulted from active fields commit)

Eevee: Don't show probe display when not using scene lighting

The display is broken otherwise.

Eevee: Fix missing UBO bind.

Merge branch 'collada' of git.blender.org:blender into collada

Benchmark: populate benchmark space from submodule.

Add Assign Material option to Special menu (W key)

Also some renames and cleanups.

Add list of color to Assign color operator

It's more clear for user to see the name of the color

Refactor Collada: Make BCAnimation class more self contained

Follwing funtionality was previously located in
BCAnimationSampler, but makes not much sense there:

* Moved the creation of the reference object into the Class constructor
* Moved the destruction of the reference to the Destructor

Furthermore:

* added get_reference() to better shield the rerference object from
unintentional access
* BCAnimationObjectMap now contains Pointers to BCAnimation objects
instead of containing full object instances. This avoids unnecessary
copying of the Animation datastructures when adding BCAnimation objects
to the BCAnimationObjectMap. Note: This forces us to delete the BCAnimation
objects in the BCAnimationSampler destructor.

Refactor Collada: Removed obsolete BCKeyPoint class

Also simplified the way how the AnimationSampler
stores its sampled data.

After some experimenting i decided to use FCurves as
intermediate storage for exported animation curves.
This looks a lot cleaner to me now because now i no
longer have duplicate storage locations.
Also the handling of curve handles is now pretty much straight
forward and no longer needs any extra calculations.

Feature Collada: Add support for Continuous Acceleration (Fcurve handles)

This allows us to create smoother FCurves during importing Collada
Animation curves. Possibly this should become an option ionstead of
a fixed import feature.

Refactor Collada: use BCKeyPoint to construct the exported FCurves

Before the handles where taken from the FCurves. But this caused
odd behavior when exporting Object hierarhcies with parent_inverse
matrices. Then the handles where calculated wrong. Now there wil be no
handles for those cases. (we might still consider to optionally
generate handles here (to be decided)

Refactor Collada: Moved check for animated curve one level up

This avoid to call the curve exporter for every curve,
regardless i it is actually exported or not.
