Allows to go to sculpt mode, do brush strokes, get out of sculpt mode
and have deformation preserved.
The issues currently is that the current implementation of CCG
storage is created from the limit surface, without displacement
taken into account. It is trivial to get displaced coordinates,
but it is more tricky to get displaced normals. This is something
to be solved next.
Another limitation is that this only works for sculpting at a maximal
multires level. There is code to be done to support propagation
of displacement onto a higher levels.
The function is supposed to be called for original object.
Draw manager abuses this a bit, will solve later by moving
PBVH (re)creation to dependency graph.
At the time being, stop adding object evaluation to draw
manager, this is really where it does not belong to.
Attempts to substitude CCGDM with an OpenSubdiv based structure
which has less abstraction levels. The missing part in this
substitude is a face pointers which old CCGDM/multires code was
using to stitch faces (averaging boundaries).
Another curial bit missing: "reshaping" of multires CD_MDISPS
to the state of new PBVH grids.
The new code is only available when OpenSubdiv modifier is
enabled (WITH_OPENSUBDIV_MODIFIER=ON) and with debug value of
128. This is so this WIP code is not interfering with current
production machines in the studio.

We would need to at least support one more PBVH building
here, trying to squeeze everything into one function will
make it really hard to read and follow.
This commit merge the full development done in greasepencil-object branch and include mainly the following features.
- New grease pencil object.
- New drawing engine.
- New grease pencil modes Draw/Sculpt/Edit and Weight Paint.
- 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.
Will help entering sculpt mode on file load by making it possible
to fully initialize sculpt session. The goal is to make sure PBVH
exists since the very beginning of file open (missing PBVH is a
reason why object is not visible before first stroke).
This is not enough yet to fully solve the issue, since entering
sculpt mode tags object for Copy-on-Write update, which frees
PBVH.
Pretty straightforward changes, merely mimicking dm-related code,
which was already essentially using either Mesh or BMesh data to
build the PBVH...
Note that we "lose" the subsurf (a.k.a. grid) PBVH case here, but that
one was already dead code in current blender2.8, since final dm is
always a cddm built from evaluated mesh.
Proper fix is pending new code for subsurf/multires area.
The function definitions still reside in DerivedMesh.c. Once we're done
porting all the DerivedMesh use to Mesh, we'll move the still-relevant
functions to mesh_runtime.c. This move is now cumbersome due to shared
statically-declared utility functions in DerivedMesh.c
* Always use BKE_id_new, unless you have a very good reason to use
lower-level code!
* Prefer to pass actual ID user pointer to functions like id_us_plus & co,
rather than 'floating' ID pointer, when possible. It makes it more clear
who is the user we increase count for!
Skip access to any evaluated data when operator is run on file load,
we don't have depsgraph evaluated yet. In this case we skip part of
sculpt session initialization, since it will be done during depsgraph
evaluation which happens after DEG_on_visible_update().
We can not skip sculpt session initialization since during normal
operation we want all the data to be initialized on mode change,
and not on initial brush stroke.
The depsgraph was always created within a fixed evaluation context. Passing
both risks the depsgraph and evaluation context not matching, and it
complicates the Python API where we'd have to expose both which is not so
easy to understand.
This also removes the global evaluation context in main, which assumed there
to be a single active scene and view layer.

- Read-only access can often use EvaluationContext.object_mode
- Write access to go to WorkSpace.object_mode.
- Some TODO's remain (marked as "TODO/OBMODE")
- Add-ons will need updating
(context.active_object.mode -> context.workspace.object_mode)
- There will be small/medium issues that still need resolving
this does work on a basic level though.
See D3037
Brushes themselves are still affected by the mask, but the viewport is not
showing the mask. This way it's easier to see details while sculpting.
Studio request by Julien Kaspar
This reverts change to BKE_brush_add,
callers now remove the extra user.
Note this isn't very convenient for callers but
is consistent with other ID types.
In the future we will probably remove this and have new
ID's created with zero users.
The RenderResult struct still has a listbase of RenderLayer, but that's ok
since this is strictly for rendering.
* Subversion bump (to 2.80.2)
* DNA low level doversion (renames) - only for .blend created since 2.80 started
Note: We can't use DNA_struct_elem_find or get file version in init_structDNA,
so we are manually iterating over the array of the SDNA elements instead.
Note 2: This doversion change with renames can be reverted in a few months. But
so far it's required for 2.8 files created between October 2016 and now.
