WIP: Readjust weight for stabilize

WIP: First test for smooth thickness

WIP: More work to get better drawing feeling

Thre was some problems in previous commits

Remap pixel scale parameter

The value for control point density was strange.

Compile fixes after merge

Cleanup: Fix compiler warnings

Cleanup: Supress compiler warning

WIP: New parameters for brushes

More parameters to define how the stroke is stabilized.

This parameters maybe are not necessary on UI, but we need them now for testing different values.

WIP: Fix error in smooth lines

Need to check the distance of previous points, not new with previous.

WIP: Reduce points when stroke is slow

Initial work to reduce the noise when the stroke is done very slow removing points not relevant.

WIP: As a temporary measure for fixing GP cache invalidation crashes,
re-enable BKE_gpencil_batch_cache_alldirty_main() when debug_value = 660

Updating the hacky eval_ctx construction to use more official functions

Fix: Added some more tags/relations in depsgraph to fix crashes when Onion Skinning is enabled

* id_tag_update_object_data() - Added a case for the GP datablock type
so that depsgraph tagging via the GPencil datablock's RNA properties
works. Previously, only the object.data case (i.e. modifiers) was handled.
This fixes a crash when enabling onion skinning, and a ghost can be shown
on the neighbouring frames.

* DepsgraphRelationBuilder::build_obdata_geom() - Added a relation between
timesource and GP geometry (i.e. where cache rebuild occurs). This fixes
a crash after scrubbing the timeline when onion skinning is enabled
(I'm guessing due to onion skinning suddenly getting re-shown, but the cache
not doesn't contain this info due to the previously being updated for animation)

Apply stabilization in segments with a minimum size

If the points are too near, the stabilization must be disabled.

This modification is still WIP, needs more artist feedback to verify if works.

Merge branch 'blender2.8' into greasepencil-object

Improve stabilization function

Now the previous point is smoothed too to get a better transition.
