EEVEE: Lookdev: Fix lookdev spheres positioning in viewport render

Fix failure to add import OpenVDB file when .blend file is saved

EEVEE: Lookdev: Fix cubemap resolution change not refreshing lightcache

Overlay: Fix overlays being washed out by render colors

Clamping here might be a bit too much if output is expected to be HDR.
But we don't support HDR atm so clamping is fine.

Start of unit test framework for constraints

Currently this only tests the Child Of constraint. My aim is to cover
constraints with tests before they are refactored/altered.

No functional changes.

Cleanup: fixed copy-paste error in Object Solver constraint message

The message was clearly copied from the Child Of constraint, and never
changed to Object Solver.

No functional changes.

EEVEE: Lookdev: Add support for partially blurred background

This is using the GGX probe as background. This has the drawback of
having the resolution choosed in the indirect lighting setting.
The blurring is not really high-quality.

The pros is that it has a simple implementation and is fast to evaluate.

This patch also fades the background alpha to make overlay engine draw the
default background color in the correct color space. Removing one colorspace
hack.

Cleanup: EEVEE: Use log2_floor_u

EEVEE: Fix seams in reflection cubemap on low roughness

This was caused by the texture size not being power of 2. Thus the
padding applied to the base LOD did not match the highest mipmaps.

GPencil: Fix time modifier

After the change of the loop, the time modifier was not evaluated.

Fix T74095: crash deleting all faces in edit mode with Cycles rendering

Cycles: move sss and diffuse transmission into diffuse pass

This simplifies compositors setups and will be consistent with Eevee render
passes from D6331. There's a continuum between these passes and it's not clear
there is much advantage to having them available separately.

GPencil: Fix crash when Sculpt with Grab brush in an empty frame

As the copy of the frame is done after the eval data is used, it could be possible the first time the stroke is not available.

Cleanup: remove cddm_from_bmesh

Use BKE_mesh_from_bmesh_for_eval_nomain instead.
