UI: move gizmo popover next to the overlay buttons

In paint modes this was the only button in the middle.

improved reuse of dummy slots in array lookup

Fix T63598: "child of" constraint "set/clear inverse" ops not working

was missing DEG updates

Fix T63377: "Principled Volume" node not working anymore in EEVEE

I'm not sur how it ever worked before. There was no texture bound to these
sampdensity and sampflame when no volume simulation was happening.

This fixes the issue using 1x1x1 dummy textures.

deduplicate some array lookup code

splitup tests for set and set_vector

don't use linear search in SmallSetVector

remove refcount class that is not used anymore

Merge branch 'cycles_adaptive_sampling' of github.com:skwerner/blender into cycles_adaptive_sampling

Adaptive Sampling for Cycles.

This feature takes some inspiration from
"RenderMan: An Advanced Path Tracing Architecture for Movie Rendering" and
"A Hierarchical Automatic Stopping Condition for Monte Carlo Global Illumination"

In addition, it implements the sampling pattern described in
"Progressive Multi-Jittered Sample Sequences"

The basic principle is as follows:
While samples are being added to a pixel, the adaptive sampler writes half
of the samples to a separate buffer. This gives it two separate estimates
of the same pixel, and by comparing their difference it estimates convergence.
Once convergence drops below a given threshold, the pixel is considered done.

When a pixel has not converged yet and needs more samples than the minimum,
its immediate neighbors are also set to take more samples. This is done in order
to more reliably detect sharp features such as caustics. A 3x3 box filter that
is run peridoically over the tile buffer is used for that purpose.

After a tile is finished rendering, the values of all passes are scaled as if
they were rendered with the full number of samples. This way, any code operating
on these buffers, for example the denoiser, does not need to be changed for
per-pixel sample counts.

Cycles: Moved "Adaptive Sampilng" option out of the advanced section in the UI.

Cleanup: Add missing comma

Industry Compat Keymap: Tool shortcuts

- Use C for Cursor tool
- Use D for Annotate tool
- Use tool shortcuts in UV Editor (although it's weak here still - waiting for Move, Rotate & Scale tools here)

pack list declaration handles implicitely convertable types

Merge branch 'master' into greasepencil-object

add LIB to CMakeLists.txt

GPencil: New Dots gradient

This commit adds support for drawing Dots strokes with a gradient factor to get artistic effects like watercolor.

Currently, the option is only supported by Dots materials, and in the future will be added to line strokes, but now there is a limitation on drawing engine and we will keep disabled on Line materials.

Also, added the option to align Dots and Boxes strokes textures aligned with the drawing path to get more fluid strokes.

Merge branch 'master' into functions

Industry Compat Keymap: Panning consistency

- Allow orbiting while using Knife tool
- Use consistent panning keys in properties lists
- Also fix warning related to empty View 3D Generic keymap
