Similar to the one allowing to deactivate DNA check, etc.
Will helps reduce verbosity when making many new properties overridable.
Note that pointer properties always remain non-overridable by default,
since basically only ID pointers should be.

This data block will be the container for simulation node trees.
It will be used for the new particle node system (T73324).
The new data block has the type `ID_SIM`.
It is not visible to users and other developers by default yet.
To enable it, activate the cmake option `WITH_NEW_SIMULATION_TYPE`.
New simulation data blocks can be created by running `bpy.data.simulations.new("name")`.

NOTE: While most of the milestone 1 goals are there, a few smaller features and
improvements are still to be done.
Big picture of this milestone: Initial, OpenXR-based virtual reality support
for users and foundation for advanced use cases.
Maniphest Task: https://developer.blender.org/T71347
The tasks contains more information about this milestone.
To be clear: This is not a feature rich VR implementation, it's focused on the
initial scene inspection use case. We intentionally focused on that, further
features like controller support are part of the next milestone.
- How to use?
Instructions on how to use this are here:
https://wiki.blender.org/wiki/User:Severin/GSoC-2019/How_to_Test
These will be updated and moved to a more official place (likely the manual) soon.
Currently Windows Mixed Reality and Oculus devices are usable. Valve/HTC
headsets don't support the OpenXR standard yet and hence, do not work with this
implementation.
---------------
This is the C-side implementation of the features added for initial VR
support as per milestone 1. A "VR Scene Inspection" Add-on will be
committed separately, to expose the VR functionality in the UI. It also
adds some further features for milestone 1, namely a landmarking system
(stored view locations in the VR space)
Main additions/features:
* Support for rendering viewports to an HMD, with good performance.
* Option to sync the VR view perspective with a fully interactive,
regular 3D View (VR-Mirror).
* Option to disable positional tracking. Keeps the current position (calculated
based on the VR eye center pose) when enabled while a VR session is running.
* Some regular viewport settings for the VR view
* RNA/Python-API to query and set VR session state information.
* WM-XR: Layer tying Ghost-XR to the Blender specific APIs/data
* wmSurface API: drawable, non-window container (manages Ghost-OpenGL and GPU
context)
* DNA/RNA for management of VR session settings
* `--debug-xr` and `--debug-xr-time` commandline options
* Utility batch & config file for using the Oculus runtime on Windows.
* Most VR data is runtime only. The exception is user settings which are saved
to files (`XrSessionSettings`).
* VR support can be disabled through the `WITH_XR_OPENXR` compiler flag.

Custom profiles in bevel allows the profile curve to be controlled by
manually placed control points. Orientation is regularized along
groups of edges, and the 'pipe case' is updated. This commit includes
many updates to comments and changed variable names as well.
A 'cutoff' vertex mesh method is added to bevel in addition to the
existing grid fill option for replacing vertices.
The UI of the bevel modifier and tool are updated and unified.
Also, a 'CurveProfile' widget is added to BKE for defining the profile
in the interface, which may be useful in other situations.
Many thanks to Howard, my mentor for this GSoC project.

Better to make internal code naming match official/UI naming to some
extent, this will reduce confusion in the future.
This is 'breaking' scripts and files that would use that feature, but
since it is not yet officially supported nor exposed in 2.80, as far
as that release is concerned, it is effectively
a 'no functional changes' commit.
Use a default update function for user preferences that tags
dirty and redraws (if changed).
This avoids relying on button changes which fail in some cases.
The goal is to prevent assignment of temporary or evaluated meshes
to objects from the main database.
Majority of the change is actually related on passing reports around.
On a positive side there are more error prints which can become more
visible to scripters.
There are still possible further improvements in the related areas.
For example, disable user counting for evaluated ID datablocks when
assignment happens. But can also happen later on as a separate
improvement.

This patch does not bring any functional change, but it does expose
some utilities that can be very useful to correct occlusion and
performance problems of Circle Select and similar.
Creating a selection context still makes it easier to track issues.
One of the usecases is to create mesh from an object is a manner similar to
how Apply Modifiers does it, and have it in the bmain so it can be referenced
by other objects.
This usecase is something what went unnoticed in the previous API changes, so
here is a followup.
Summary of changes:
* bpy.meshes.new_from_object() behaves almost the same as before this change.
The difference now is that it now ensures all referenced data-blocks are
original (for example, materials referenced by the mesh).
* object.to_mesh() now creates free-standing Mesh data-block which is outside
of any bmain. The object owns it, which guarantees the memory never leaks.
It is possible to force free memory by calling object.to_mesh_clear().

Main goal here is to make it obvious and predictable about
what is going on.
Summary of changes.
- Access to dependency graph is now only possible to a fully evaluated
graph. This is now done via context.evaluated_depsgraph_get().
The call will ensure both relations and datablocks are updated.
This way we don't allow access to some known bad state of the graph,
and also making explicit that getting update dependency graph is not
cheap.
- Access to evaluated ID is now possible via id.evaluated_get().
It was already possible to get evaluated ID via dependency graph,
but that was a bit confusing why access to original is done via ID
and to evaluated via depsgraph.
If datablock is not covered by dependency graph it will be returned
as-is.
- Similarly, request for original from an ID which is not evaluated
will return ID as-is.
- Removed scene.update().
This is very expensive to update all the view layers.
- Added depsgraph.update().
Now when temporary changes to objects are to be done, this is to
happen on original object and then dependency graph is to be
updated.
- Changed object.to_mesh() to behave the following way:
* When is used for original object modifiers are ignored.
For meshes this acts similar to mesh-copy, not very useful but
allows to keep code paths similar (i.e. for exporter which has
Apply Modifiers option it's only matter choosing between original
and evaluated object, the to_mesh() part can stay the same).
For curves this gives a mesh which is constructed from displist
without taking own modifiers and modifiers of bevel/taper objects
into account.
For metaballs this gives empty mesh.
Polygonization of metaball is not possible from a single object.
* When is used for evaluated object modifiers are always applied.
In fact, no evaluation is happening, the mesh is either copied
as-is, or constructed from current state of curve cache.
Arguments to apply modifiers and calculate original coordinates (ORCO,
aka undeformed coordinates) are removed. The ORCO is to be calculated
as part of dependency graph evaluation.

Access to main database is actually rarely needed, but some custom
'apply' functions do need it (like Collections' overriding of objects or
children collections).
OVERVIEW
* In 2.7 terminology, all layers and groups are now collection datablocks.
* These collections are nestable, linkable, instanceable, overrideable, ..
which opens up new ways to set up scenes and link + override data.
* Viewport/render visibility and selectability are now a part of the collection
and shared across all view layers and linkable.
* View layers define which subset of the scene collection hierarchy is excluded
for each. For many workflows one view layer can be used, these are more of an
advanced feature now.
OUTLINER
* The outliner now has a "View Layer" display mode instead of "Collections",
which can display the collections and/or objects in the view layer.
* In this display mode, collections can be excluded with the right click menu.
These will then be greyed out and their objects will be excluded.
* To view collections not linked to any scene, the "Blender File" display mode
can be used, with the new filtering option to just see Colleciton datablocks.
* The outliner right click menus for collections and objects were reorganized.
* Drag and drop still needs to be improved. Like before, dragging the icon or
text gives different results, we'll unify this later.
LINKING AND OVERRIDES
* Collections can now be linked into the scene without creating an instance,
with the link/append operator or from the collections view in the outliner.
* Collections can get static overrides with the right click menu in the outliner,
but this is rather unreliable and not clearly communicated at the moment.
* We still need to improve the make override operator to turn collection instances
into collections with overrides directly in the scene.
PERFORMANCE
* We tried to make performance not worse than before and improve it in some
cases. The main thing that's still a bit slower is multiple scenes, we have to
change the layer syncing to only updated affected scenes.
* Collections keep a list of their parent collections for faster incremental
updates in syncing and caching.
* View layer bases are now in a object -> base hash to avoid quadratic time
lookups internally and in API functions like visible_get().
VERSIONING
* Compatibility with 2.7 files should be improved due to the new visibility
controls. Of course users may not want to set up their scenes differently
now to avoid having separate layers and groups.
* Compatibility with 2.8 is mostly there, and was tested on Eevee demo and Hero
files. There's a few things which are know to be not quite compatible, like
nested layer collections inside groups.
* The versioning code for 2.8 files is quite complicated, and isolated behind
#ifdef so it can be removed at the end of the release cycle.
KNOWN ISSUES
* The G-key group operators in the 3D viewport were left mostly as is, they
need to be modified still to fit better.
* Same for the groups panel in the object properties. This needs to be updated
still, or perhaps replaced by something better.
* Collections must all have a unique name. Less restrictive namespacing is to
be done later, we'll have to see how important this is as all objects within
the collections must also have a unique name anyway.
* Full scene copy and delete scene are exactly doing the right thing yet.

This patch adds support for:
- Per space-type tools (3D view and edit).
- Per mode tools (object, edit, weight-paint .. etc).
The top-bar shows the last activated tools options, this is a design
issue with using a global topbar to show per-space settings.

We are bumping the subversion.
Pending tasks:
* Tile/clamp code in image editor draw code.
* Viewport drawing code (so much of this will go away because of BI removal
that we can wait until then to remove this.
For correct results these must have been set already when the depsgraph was
created and evaluated, so all dependencies have appropriate resolutions too.
For particle we no longer backup and restore the viewport particles to avoid
overwriting them during render, as copy-on-write solves this for us. Even
without COW particles seem to work ok.
This also removes the particle simplification options based on camera. This
was never used much and only available in Blender Internal.
