- Use smooth normals to displace in Above Surface mode.
- Add an option to align an axis to the normal in the constraint.
I've seen people request the alignment feature, and it seems useful.
For the actual aligning I use the damped track logic.
In order to conveniently keep mesh data needed for normal
computation together, a new data structure is introduced.

There were a few copies of the same few lines in depsgraph build code,
so it seems to be logical to introduce a function for it, and make it
accessible from C code for completeness.
As an example, register the mask needs of the Data Transfer modifier.
Before it was only doing this for directly linked objects. This was
initially needed to solve fps issues in some of the shots. Now this
fps drop i can no longer reproduce. Was likely needed prior to
modifiers dependencies "inheriting" visibility from the "parent".
This commit makes it so objects which are linked indirectly to the
scene via collections are properly considered visible (or, rather,
evaluatable) by dependency graph.
Solves missing eyelashes and braids issues with 01_035_A.
Previously it was possible to have geometry component to
tag batch for DIRTY_ALL and shading to tag with SHADING_UPDATE.
Now there is a relation between uber eval and shading, which
solves this issue.
The idea of those flags is to avoid evaluation of operations
which are not needed to bring visible objects to an up to date
state.
Previously, dependency graph attempted to do combine those
into an ID level flag. In practice it proved to be rather
tricky, since there could be dependency cycles on ID level
which will not exist on component level.
This allows to force duplicated object to be fully evaluated for
display/draw.
Previously only transform component of duplicated object was
forced to become evaluated.
Need to ensure objects from collection which was built but
is became visible in the new "context" are poked for re-built.
This should be rather cheap, since this only will update
their visibility flag.
Can not rely on visibility flush here, since there is no
relations between collection and its objects.
Avoids invisible objects from being considered visible when they
are used as driver variables.
If those cases are actually coming from a visible object, then
deg_graph_build_flush_visibility() will ensure visibility is
properly flushed there.
Was happenign for following cases:
- Deep hierarchy of non-restircted collections, which has grand-grand
parent restricted.
- Collections which are constructed from invisible object.
The title says it all actually, the idea is to speedup the following case:
- Visible duplicator of a restricted collection (reported as T56512),
One of the questionable change is that none of the view layer bases is
ignored now. This ensures corresponding objects will have copy-on-write
component evaluated, making it possible to access those pointers. The
evaluation of those objects is skipped.

This includes selections both in the clip editor as the viewport.
The selection is implemented as a synchronization function called from the eval
selection update node in depsgraph.
Some constraints have an option to take the final bezier shape of
the target B-Bone into account. This shape usually depends on two
other bones in addition to the target itself, so the graph should
include the relevant dependencies.

- New brushes for grease pencil.
- New modifiers for grease pencil.
- New shaders FX.
- New material system (replace old palettes and colors).
- Split of annotations (old grease pencil) and new grease pencil object.
- UI adapted to blender 2.8.

This is the result of nearly two years of development and I want thanks firstly the other members of the grease pencil team: Daniel M. Lara, Matias Mendiola and Joshua Leung for their support, ideas and to keep working in the project all the time, without them this project had been impossible.
Also, I want thanks other Blender developers for their help, advices and to be there always to help me, and specially to Clément Foucault, Dalai Felinto, Pablo Vázquez and Campbell Barton.
