GPencil: WIP use resolution parameter, pressure and strength

GPencil: Add resolution parameter to bGPDcurve

UI: Drag and Drop FModifiers, Layout Updates

There are still problems
- Context doesn't work in NLA editor
- Lots of memory leaks for anim context.
Should find a different method for getting the context that doesn't require a "free" every time.

This also adds support for regions with panel categories to the list panel system, which was a simple oversight.

Differential Revision: https://developer.blender.org/D7997

Merge branch 'master' into greasepencil-edit-curve

List panel system: Support regions with categories

Outliner: Add activation and toggle to left column buttons

The buttons in the left column didn't work, and in the first step that
they did work, I only added support for camera objects. This adds
support for edit mode toggling and collections and scene activation.
Previously clicking in the column for those types would crash.

GPencil: Initialize curve resolution for new objects

GPencil: Add resolution to strokes panel

GPencil: Move geometry functions to right module

These functions were not moved in a previous refactor

GPencil: Pass gpd datablock to BKE_gpencil_stroke_geometry_update

This is needed to get curve edit data parameters

GPencil: Add new edit_curve_resolution prop

This will be used to define the qualitty of the generated stroke.

EEVEE: Motion Blur: Expose max blur and depth scale

Fixes for changes in master after last merge

Merge branch 'asset-uuid' into asset-engine

Fluid: Added an option for grid scaling in Color Mapping.

EEVEE: Motion Blur: Fix camera near/far values uniforms

EEVEE: Motion Blur: Replace Wang Hash Noise function by blue noise

Fix Wrong struct reference.

Merge branch 'greasepencil-edit-curve' into soc-2020-greasepencil-curve

GPencil: Convert from curve to stroke in update_geometry

Call the function BKE_gpencil_stroke_update_geometry_from_editcurve
in BKE_gpencil_stroke_geometry_update and force
an update when curve handles change position in RNA.
