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.

GPencil: Refactor: Add Glow effect

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

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: Add Shadow Effect

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

GPencil: Fix Layer UI

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.
