Merge branch 'blender2.8' into greasepencil-object

Fix error when rotate using 3D cursor

The rotation of the strokes must use cursor in local space.

Merge branch 'blender2.8' into greasepencil-object

Fix error when make single user

Fix memory leak

Fix error with user number

When apply array modifier the gpd is not reused, so the us must remain equal.

Fix error when apply Array with more modifiers

When apply an array modiifer is necessary to create new GP datablocks and remove in the duplicate object the array modifier to avoid double effect.

Fix error if apply modifier with multi-user GP

The modifier cannot be applied if the GP datablock is used for more than 1 objects.

Set all default HSV range to 1

Fix error when apply color related modifiers

The effect was duplicated for each stroke and the result was wrong

New Hue/Saturation modifier

Opacity modifer affect strength

If the factor is > 1, the strength of the stroke is affected by modifier

Clamp to valid range

Remove object control for Opacity

There was several problems to use an object to control opacity and how change fill opacity, so it's better to remove this and find an alternative (maybe using shaders)

Cleanup: Remove double initialization

The minmax function does this initialization.

Filter index pass only if > 0 in modifiers

If the pass index is equal to 0, the filter is disabled. This is a handy way of reset the filter without adding new flags.

WIP: Basic implementation of Opacity modifier

Still pending the target functionality.

Add Set Origin to Geometry

New option to set origin at the center of the strokes of the current frame.

Cleanup: Remove unused variables

Fix error duplicating object with modiifers
