Fix T72289: FreeStyle python error

Introduced by {T67981}. We changed the python API for curve evaluation.
Freestyle still used the old call that failed. This patch updates
FreeStyle to use the new API. I checked other areas in freestyle but it
seemed to be the only `evaluate` for curves that is called directly.

Fix T72353: Camera Limits Visibility

Due to recent refactoring of the overlay unification the camera limits
were also visible when the overlays were turned off. This was because
the `draw_extra` had an exception for when looking through the camera.

This change also takes the global hide overlays into account. So now the
camera limits will not be drawn when overlays are turned off. This also
fixed other camera related overlay drawing.

Fix T72124: LookDev Sphere Rendering

Due to the refactoring of the overlay engine the draw caches were
changed. The sphere batch used to have positions and normals. After the
refactoring it didn't had the normals anymore. The normals are needed
for shading. As they were not there the look dev spheres were rendered
black.

This change add the `nor` attribute to `DRW_cache_sphere_get` batch.

GPencil: Replace hardcoded factor by definition

Merge branch 'greasepencil-object' into greasepencil-refactor

Merge branch 'master' into greasepencil-object

Remove Action Context concept for now

Merge branch 'master' into functions

Cleanup: remove unused gesture event.

GPencil: Fix Layer UI

GPencil: Refactor: Add Shadow Effect

All the parameters are now locked in world space following the object
center.

GPencil: Refactor: Add Glow effect

The glow effect is now additive. You cannot make black "glow" (whatever
that meant).

GPencil: Refactor: Add Pixelize effect

Bonus: the pixelize effect use the center of the object as pixelization
center. This improves stability of the effect.

We also use a 2pass downsampling to reduce the flickering.

The pixel size is now fixed in world space and dependant of object scale
and distance to camera.

GPencil: Refactor: FX: make the Blur not dependant on sampling parameter

The sampling parameter was in fact use as iteration step count in previous
implementation. New behavior is much more consistent and predicatble

GPencil: Refactor: Add invert masking

GPencil: Refactor: Base implementation of VFX for gpencil

This new implementation is clearer and also process the colored alpha
compoment to preserve blending informations.

This is the base implementation containing a placeholder blur.

All the real effect implementation will follow in separate commits.

Fix error assigning the fluid particle flag to the wrong member

Fix linking errors WITH_MOD_FLUID=OFF, again

Expose BKE_fluid_modifier_* functions for readfile versioning.

Image Editor: Load UDIMs even if secondary tile is selected

Previously the user had to select the 1001 tile for this to work,
now any tile will work as long as the 1001 tile still exists on disk.

Cleanup: use ELEM macro
