GPU: Make node texture "Blend" parameter interactive.

This parameter is only used for Box projection type.

Workbench: Improve volume render by removing noise using temporal AA

Workbench: Fix volumetric blending leading to corrupted render results

Use simpler premultiplied blending.

Workbench: Fix non transparent background in viewport render

Eevee: Wireframe: Increase precision a bit

Take the full derivative and compute its length instead of using fwidth.

Eevee: Make Normal node interactive

Before it was triggering shader recompilation. Include small cleanup/opti.

GPU: Fix wrong socket value struct

This was causing bad behavior of the node Normal.

Eevee: Fix non normalized Normals in BSDFs and Layer Weight

Although the normal was normalized when evaluating the lighting, the normal
is often used for other purpose. In this case using the non normalized
normal maybe the source of errors.

GPU: Cleanup: Vectorize operations and use MADD

Eevee: Improve Hashed Alpha transparency by reducing noise size

This only affect renders and static viewport accumulation.
It reduces helps reduce noise when lots of half transparent surfaces
overlaps.

Eevee: Support monochromatic Transparent BSDF correctly

This fits Cycles better even if it is only for grey scale values. This only
work if the blend mode is Alpha Blend or Alpha Hashed.

Cleanup: naming (inconsistent paint_mode term)

Cleanup: use BKE_brush_tool_get/set macros

Also add API call WM_toolsystem_ref_sync_from_context
(was in rna_workspace_api.c)

Paint: bring back brush switching

Was temporarily replace with code that used the tool-system,
bring back logic which cycles and toggles brushes.

Tool slots are used for the initial brush,
after that toggle or cycle is used.

Paint: fix for creating duplicate brushes

Setting the tool added a brush if none was found
but wasn't checking for existing brushes.

Paint: correct brush defaults

Cleanup: style

UI: Move pin icon to the right in the context breadcrumbs.

Leaves more room for the actual breadcrumbs path, and it's less intrusive.

Thanks Luciano for the suggestion!

UI: Use icons for some operators.

* Area and Workspace duplicate.
* Toggle Area Fullscreen
* Operator Search
* Workspace reorder to front/back (arrows help to know which direction means front/back)

Fix broken shortcuts in F3 'operator search' menu.

From own changes in that area... Now we also enforce handling shortcuts
in case relevant drawflag of searchbutton is set. Should allow to cover
all cases, hopefully.
