Was initially reported when painting on a mesh with armature,
which was failing due to missing bbone cache. The issue was
deeper, and was related on the way which object was used to
calculate crazyspace.
The layout changed when the radius property was added to shape
keys in 2.8, but the RNA code wasn't updated.
Also, even before that, the code didn't do anything to correctly
handle mixing sub-curves of different type (nurbs vs bezier) in
the same Curve object. Now that case is handled correctly but not
very efficiently by allocating a mapping table when necessary. To
recover some performance, a custom index lookup function is added.
When enable annotations with a grease pencil object, the GP Object must be set to Object mode because the annotation Draw and the GP draw are incompatible.
Solves weird situation when default display name is queried
from OCIO, but Default view being assumed to be set for it.
Now view is initialized to a default view of that display.
That one was flagged as useless since 2.77, and only kept 'to be sure'
everything was OK. This was years ago now, and never got any report on
this, so 2.8 sounds like a good time to nuke it.
Passing depsgraph instead of scene, since a scene does not fully define the
state of object you want to use for the BVH.
Also, mesh_create_eval_final_view and mesh_create_eval_final_render are pretty
much the same, so mesh_create_eval_no_deform and
mesh_create_eval_no_deform_render are as well.

No functional changes, but it makes all the coordinates more consistent
(going from small to larger values). It helps debugging in the future
to be able to rule out vertex order as a culprit.
The top-left and bottom-right corners were creating the new area in the
wrong place.
Blender 2.7x only had action zone corners in the top-right, and
bottom-left corners. So it had some hardcoded assumptions based on that.
This commit feels a bit like a hack, but I think it may be fine.
Bug reported via IRC, how to reproduce:
* Change shading to Rendered.
* Split viewport from the top-left corner.
Since it seems that CD_ORIGINDEX is not available for loops,
the only choice is to simply use the loop normals already
computed by depsgraph after evaluating modifiers.
This revealed a bug where the Auto Smooth settings would be lost
from the mesh after complex modifiers, or after edit mesh to mesh
conversion, so restoring them is needed to get correct results.
This only happens after a certain wireframe threshold.
We sort triangles into 2 bins (start and end of the buffer) based on a
threshold and just draw the first bin if the wireframe slider is low enough.
This optimization is disabled for deformed meshes when playback is active.
This optimization is only implemented for meshes object for now.
This should help resolve (to some extent) T58188.

The issue was caused by transflag set in geometry evaluation
never copied back top original object.
Now we have a dedicated operation which does all sort copy
back to original object, so we don't have to worry about
atomic assignments or what gets set where.
Still need to move boundbox to the same function, but it
needs some careful doublechecking first.
This seems to be a bug in OpenSubdiv. For now simply use Catmark
subdivision scheme with infinitely sharp edges.
Later on it's either gets fixed in OpenSubdiv or we do bilinear
subdivision on our side.
All localized datablocks are not supposed to have animation
data associated with them.
There was an easy way to reproduce assert failure: toggle
animation decorator for Viewport Display -> Color.
