Remove Grease Pencil Color Picker

This operator has been replaced by the new preview system.

Update previews when change material

Also split rna update for grease pencil parameters

Fix grease pencil cache update problems when change material properties

Since commit f84956738ba4e97f30553a675b643f6648afce1d 6/07/2018 12:33, the update of the materials was not working because depsgraph only update the current ID and not all related.

This fix the issue but need a review.

@aligorith Could you take a look and check if this is the best solution, I'm not sure about the fix, maybe we could add a relationship between material and datablock when create a new material.

Fix merge error and remove old code

This file was wrong from a previous merge and still had code about grease pencil modifiers that was not deleted when the GP modifiers were splitted.

Merge branch 'blender2.8' into greasepencil-object

WIP: Define a new preview blend file for grease pencil

The blend file is only a copy of old file. Put only as placeholder.

Merge branch 'npr_tess' of https://github.com/DarkDefender/blender into soc-2018-npr-tess-modifier

Modify code to standard api and style

Cycles: Bug fixes

- Stopping recursive tree traversal if
negative PDFs are encountered.

- accum_light_tree_contribution() now
takes a scale factor as input which
is passed through to accum_light_contribution

- light_bvh_sample now changes randu. This
is similar to the other *_sample functions.
This fixed a bug where recursive traversal
with no splitting gave a different result
compared to just using light_sample.

Cycles: Updated SAOH with regularization factor

This factor penalizes thin bounding boxes in
the tree construction.

Cycles: Updated cone aggregation and measure

The paper provided a way to merge two bounding
cones and an updated version of the cone
measure.

Cycles: Updated the importance metric

The new paper provides an updated importance
metric which is now implemented. Also, a bug
in the index used for background lights in
the MIS calculations have been fixed.

Technical details:
- The new importance metric depends on the
normal at the shading point. The MIS
calculations have been changed
accordingly.

- The uncertainty angle was described in
the paper and is now implemented.

- In the implementation details section
of the paper they mention that they
limit the distance if splitting is
disabled. This is implemented too.

Cycles: Updated rescaling of random numbers

The new paper describes how they rescale the
random numbers in the tree traversal. We do
the same now.

Cycles: Updated the split heuristic

The split heuristic is now based on the
new paper instead of the abstract/slides
from 2017.

Move depsgraph tag after brush creation

If the brush was created, the tag was not working because it was done before the brush was available.

Move Overlay options to View3DOverlay

It's better to keep all overlays in the same RNA.

fix for smoke guiding and some cleanup
