Cleanup compiler warnings

Define keys to switch grease pencil modes

WIP: Initial implementation for paint mode

The paint mode need more work, but it start to work.

WM: add WM_manipulatorgrouptype_append_ptr

Needed for PyAPI registration.

WM: de-duplicate operator append code

WM_operatortype_append(_ptr) functions had diverged.

PyAPI: is_staticmethod used for classmethods's too

Add note to investigate this, don't change so close to release.

PyAPI: correct exception, expect 'staticmethod'

DwM: skip background-set objects w/ selection

Fix alembic tests not running with debug build on windows

Clay Engine: Improve sampling of SSAO

Replace completly random noise by Blue noisen, giving a better aspect.
Also randomize the distance in the sample direction to cover the whole distance even with 1 sample. Using another blue noise for this.
Replace spiral samples (that had tendency to align if the number of samples was near the chosen constant) with Hammersley samples that have good coverage even for low number of samples.
Use a UBO instead of Texture (a bit less latency) making things a tiny bit faster.
Move the noise data to the SceneLayerData, because each render layer can have a different sample count.

Eevee: Modify Blue Noise.

Eevee: Move Spherical Harmonics to a new Probe UBO.

Keep data packing tight to prevent use of padding floats

Cleanup: Remove unused code to set mode

This code is not used anymore in viewport with new modes

WIP: Basic structure for new object modes

Now there are 3 modes: Edit, Paint and Sculpt strokes.

These modes are only for new GP object.

Notice: Now the paint and sculpt modes can be activated but don't work.

Eevee: Material code refactor.

Separate material handling inside another file.
Make use of enums to identify shader variations.
Group all 64*64 LUTs into one array texture.
Only update world probe if world changes.

World: Add temporary update flag.

Remove Edit Strokes mode for scene

This mode is not necessary because the mode is added at object level and the scene level is not available anymore.

Fix T51587: Blender fails to interpret a specific layer in OpenEXR multilayer file

PyAPI: Cleanup "Python API Overview" doc

Reword to clean up some odd grammar (mostly dangling modifiers) and
improve readability.

Fix T51691: Shear cursor input scales w/ zoom

Use relative value from cursor movement.
