Cleanup: GPencil remove DRW_ prefix for internal functions.

The prefix DRW_ must be used only for modules inside Draw Manager and not in the Engines.

Fix compositor preview not respecting un-keyed changes

This is a part of T66099.

GPencil: Fix Control points of primitives clampoed by Stencil

The control points were clamped to the stroke thickness due the last stencil change.

Now, the shading group is not clamped.

Build environment: Update OpenSubdiv to 3.4.0 RC 2

Newer OpenSubdiv brings fixes and improvements for non-manifold meshes,
which fixes some crashes we've experienced in the recent past when using
Gregory patches.

Additionally, thing new version of OpenSubdiv brings sparse patches,
which allows to multi-thread topology refinement step.

Eevee: Make use of dual source blending for volumetric resolve

This simplify the code and add an example use of dual source
blending.

DRW: Add DRW_STATE_BLEND_CUSTOM

This one enable dual source blending, enabling more fine tuned
blending parameters inside the shader.

Cleanup: de-duplicate flag checks for button colors

Fix T66171: Cycles OSL trace() crashing in displacement shaders

This is not supported, meshes do not exist in the BVH before displacement.

Tests: speed up render tests by running multiple in the same process

Blender startup time and shader compilation is a big factor when running
hundreds of tests, so now all renders in the same ctest run in the same
process.

This was previously reverted due to skipping other tests when one test
crashed. Now if a test crashes, Blender is re-run with the remaining
tests so we get results from them still.

Cleanup: clarify WM_gizmoconfig function naming

Fix: Text Location lost X/Y text

Use PROP_XYZ instead, and user Slider=True to make them display as sliders in the UI

Tool System: don't unlink gizmos when changing tools

Needed for tools not to unlink each other with multiple windows.

Fix switching tools with multiple windows & gizmos

The gizmo would only added if the gizmo type wasn't already linked.

Cleanup: error in last commit

Cleanup: remove unused context check in toolsystem_ref_link

Also comment corrections.

Tool System: don't unlink tools when changing workspaces

Caused gizmos to be lost with multiple main windows whenever one of them
switched workspaces.

Rely on tool gizmos poll function to unlink to gizmo.

Cleanup: GPencil Clarify comment

GPencil: Change HSV modifier to use the same range of parameter that other areas of Blender

The value of the Hue must be between 0 and 1, but the value was between 0 and 2.

GPencil: Change "lock_material" tooltip and text

The old name was not clear. Detected while writting the manual.
