This further changes the preferences organization, to avoid grouping unrelated
settings together. With more sections we can also expand more panels by default,
making it possible to quickly go through sections and see the settings of each.
Panels with less used settings are still collapsed by default, to keep all panel
headers visible without scrolling.

This is still not fully correct, since the event loop is blocked by GHOST
and no timer events are happening for animation while the mouse is still.
But for the most part it looks ok.
When use the Alt mode to draw close strokes, if the color had the stroke diabled, the stroke was not visiblle while drawing.
Now, it's visible while drawing, but it's hidden again when the stoke is finished. To display close strokes, enable stroke mode in material or enter in edit mode.
There was no documentation at all, some very bad practices (like using
G.debug_value > 0 as some sort of global debug print switch), and even
an overlapping use of '1' value...
Also, python setter did not check for valid range (since this is a
short, not an int).
That one was used to allow specifying in system console a new path for
missing libraries, when loading a .blend file.
We now have a much more easy and user-friendly way of repairing missing
linked datablocks/libraries, so this is not needed anymore.
Main idea is to remove IDs to be deleted from Main, to avoid looping on
them to remove other deleted IDs usage (this is the most expensive
process in ID deletion, by far).
Speed improvements when deleting a large amount of IDs from a Main
containing a lot of them is quite significant, some examples for Objects:
* Removing 1k from 10k: 32% quicker (2.5s to 1.7s).
* Removing 10k from 20k: 60% quicker (59s to 23s).
* Removing 20k from 20k: 99.5% quicker (82s to 0.4s)!
Note however that this process is more risky/touchy, since we by-pass
some safety checks from regular ID removal here.
So will only give access to that code from python API for now (in
separate commit), so that it gets really tested. Also still need to
think about how to hook it up in UI (probably mostly for Outliner),
since we often do higher-level operations there...
Seems to be caused by cae3750 which changed free() function used
by bmain free to the one which does dependency graph tag. We do
no want to do any tags here.
This commit makes it so OpenSubdiv's topology refiner is kept
in memory and reused for until topology changes. There are the
following modifications which causes topology refiner to become
invalid:
- Change in a mesh topology (for example, vertices, edges, and
faces connectivity).
- Change in UV islands (adding new islands, merging them and
so on),
- Change in UV smoothing options.
- Change in creases.
- Change in Catmull-Clark / Simple subdivisions.
The following limitations are known:
- CPU evaluator is not yet cached.
- UV islands topology is not checked.
The UV limitation is currently a stopper for making this cache
enabled by default.
C++11 doesn't need the space between '> >' in a nested templated
declaration, so instead of `std::vector<std::pair<a, b> >` we can now
write `std::vector<std::pair<a, b> >`.
It's now possible to export curves and NURBS as mesh data to Alembic.
This allows artists to do any crazy thing on curves and export the
visual result to Alembic for interoperability with other software (or
caching for later use, etc.). It's an often-requested feature.
This works around T60503 and the fixes export part of T51311.
Note that exporting zero-width curves is currently not supported, as
exporting a faceless mesh (e.g. just edges and vertices) is not
supported by the mesh writer at all.
To test, create a curve with thickness (for example extruded), export to
Alembic and check the 'Curves to Mesh' checkbox in the export options.

I moved most of the `AbcMeshWriter` code to a new class
`AbcGenericMeshWriter`. The latter is an abstract class and does not
make any assumptions about the type of Blender object being written.
This makes it possible to write metaballs, curves, nurbs surfaces, etc.
as mesh to Alembic files.
The `AbcMeshWriter` class now is the concrete implementation of
`AbcGenericMeshWriter` for writing mesh objects.
