Improve thickness fix when no locked axis

There was some problems with the thickness when the axis was not locked that were not fixed in previous commit.

Merge branch 'blender2.8' into greasepencil-object

Fix error when axis not locked

The size of the stroke was not correct when the axis was not locked.

It needs a vector to the view to calculate the real size of the stroke.

Redo Fix in previous commit and add missing lines

UI: Remove deprecated property

The OBJECT mode was removed as property.

New parameter to adjust stabilization

Parameter to control the stabilization amount of the brush.

This stabilization works as a dynamic smooth using the previous points to calculate the estimated position and average the position to get smoother strokes.

This is not a replace of smooth factor that works after finish stroke. This new parameter is applyed while drawing before ending the stroke.

Fix: Depsgraph was complaining in debug mode about the "geometry_eval" opnode for GPencil not having any function attached

In future, maybe we should move the derived_gpf calculations
(and by extension, the modifier-evaluation loops) into the
BKE_gpencil_eval_geometry() callback added in this commit.

WIP

GP drawing: Try to init the eval_ctx from draw_ctx, if C isn't provided

Smooth new points while drawing

A new smooth algorithm is used for each new buffer point using the last two points to calculate the estimated position and average this point with the current mouse position.

This smooth reduce the jitter of the stroke and allows to use lower post smooth values to reduce stroke change after finish stroke.

Now the factor is hardcoded, but after some more testing maybe we need add a parameter by brush.

Fix delay cleaning previous frame when drawing

The fast drawing was not cleaning the previous frame when the artist create a new one and only was redraw after release mouse.

Fix crash on trying to save files with GP objects

Quick fix for context being NULL when the thumbnail renderer gets triggered
while trying to save files.

TODO: We need a better solution here for passing eval_ctx down to GP modifiers
