The initial design assumed that there was only one object for each unique name, but that was not the case when instances were created.
Now, instances are supported and speed has been greatly improved when repetitions are used.
As a result of this change, the option to create objects has been removed in the Instances modifier. This option was strange and was also against Blender's design rules, since a modifier should never create objects. The old functionality of the modifier can be achieved with instances.
Also, several memory leakage problems that were not previously detected have been eliminated, and especially in the grid and in the drawing process
Onion Skin is not supported in multi-user datablocks. Support this, makes incompatible with instances. We need find a solution in the long term, but now it's better keep disabled and make instances work. Anyway, the new instances makes unnecessary to use muli-user datablocks.
Adds a displacement support for OpenSubdiov based subsurf object implemented
as a callback which gives vector displacement in object space. Currently is
implemented to calculate displacement based on myltires displacement grids,
but we can support things in the future if needed.
Submitting to review to see if there is something obviously wrong in the
direction (old multires code was sharing same displacement code to both
calculate final displaced mesh and reshape an existing one, which is rather
confusing and probably can be done more cleanly?).

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.
Related to T56363, this is not fixing the root of the bug, but ID
copying should always be a good occasion to ensure sanity of our data
(and error checking is always better than a crash!).
Currently no functional changes, just exposes all settings which we need
for OpenSubdiv, similar to what Subsurf modifier is doing already.

Currently constraints can only read the location along the
spline. This obviously limits opportunities for complex bone
interactions in rigs.
This patch exposes access to rotation and scale as well in
Copy Transforms. However, due to the way how things work,
this data cannot be smoothly interpolated, and abruptly
changes when switching to the next segment.

Scale is a multiplicative quantity, so adding it doesn't make sense.
However, for backward compatibility reasons, and in case somebody
actually desires the old additive behavior, the old way remains as
an option.
Without this change the only way to properly combine scale is via
parenting or the complicated Transformation constraint.
The new mode is turned on by a flag for file compatibility, but the
RNA option is reversed so that the new behavior feels more default.

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.

For users it defines how accurate vertex positions are in terms
of limit surface (as in, how close the vertices locations to the
condition when they are calculated for an infinitely subdivided
mesh).
This affects things like:
- Irregular vertices (joint of 3 or more edges)
- Crease
Keep quality value low for performance.
NOTE: Going higher does not necessarily mean real improvement
in quality, ideal case might be reached well before maximum
quality of 10. Quality of 3 is a good starting point.
Internally quality is translated directly to adaptive subdivision
level.

Beautiful example of typo going unoticed and firing back up in totally
unexpected place years later. Guess nobody actually duplicated a Clip
data-block before! :P
Most likely own fault, during refactor of ID copying code.
There are following reasons to do so:
- The plan is to replace it with some sort of object or viewport option,
so we can apply OpenSubdiv subdivisions on top of modifier stack and
keep modifier stack purely CPU side.
This will solve issues when adding some relation in scene will force
modifier to be evaluated on CPU.
- With new upcoming OpenSubdiv based CPU modifier implementation we can
cache topology similar to what GPU side was doing, which will already
be reasonably faster.
- OpenSubdiv GPU does not work since the OpenGL version bump, and is
to be rewritten with all the adaptive refine options kept in mind.
Since OpenSubdiv GPU was already broken and was only causing object
to become invisible, there is no reason to keep having that option in
the modifier.

This replaces old single toggle option to subdivide UVs with
an enum which can have more options. The usecase for this is
to be compatible with other software. But we also might choose
different subdivision type as default in the future.
DNA and underlying code supports all possible options, but
only the ones which are compatible with old subdivision code
are currently exposes.

C-API is way smaller than the rest of the code which uses it.
So better to conditionally compile stub implementation than
to keep adding ifdef everywhere.
new background image/clip of Camera ID was totally wrong, down the old,
broken 'way it used to be' instead of using new, more generic system.
Those ID pointers were not even added to library_query.c file, shame! xD
Enabled infinite sharp patches for topology refiner and evaluator,
which allows to have sharp edge at first subdivision level.
Also tweaked crease export from Blender to OpenSubdiv to have more
artistic control over the whole 0..1 range.
