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.

Merge branch 'blender2.8' into hair_guides

Merge branch 'blender2.8' into greasepencil-object

More cleanup...

Move WeightedNormal modifier together with NormalEdit one in menu.

Though this breaks alphabetical order, it makes much more sense to have
those two together...

More cleanup...

obvel velocity fix, disabling surface tension and viscosity for now, set do not delete flip in obstacle

More style cleanup, renaming some now-public functions.

Tweaks to UI.

Fix missing break in switch block.

Merge branch 'master' into soc-2017-normal-tools

Fix compiler error

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.
