This makes it possible to turn data-blocks into assets and back into normal
data-blocks. A core design decision made for the asset system is that not every
data-block should be an asset, because not every data-block is made for reuse.
Users have to explicitly mark data-blocks as assets.
Exposes "Mark Asset" and "Clear Asset" in Outliner context menus (currently ID
Data submenu) and button context menus. We are still not too happy with the
names, they may change.
This uses the new context members to pass data-blocks to operators, added in
af008f5532 and 0c1d476923.

This feature is intended to generate Microsoft Compiled HTML Help files
which is not something we use/need.
This also fixes an error in generation because the executable cannot be
found.
Since add-ons now unregister on exit
(as of fa566157a5)
clearing functions in `bpy.app.handlers` caused an error on exit.
Resolve by restoring handlers before exiting.
While not full width this gives a nice trade off between improved screen
use space and readibility.
The old value was 80 so this gives 25% more screen space.

Fully revert D7913 "Fix T77276: Generating Python API docs raises many warnings"
{D7913} broke xrefs/links to other types and permalinks in the docs. This makes the python api docs for 2.90 and 2.91 completely unusable.
It got partially reverted in commit e893430a63. That didn't fix those two issues though, so it should be fully reverted.
As you can see here, i'm not able to click `bpy_struct.id_data`, because no <a> tag got generated in the html.

Especially with new undo/redo it is even less recommended to perform
complex operations in those callbacks, they should remain as fast and
localized as possible.
Also updated the section about undo/redo a bit.
This commit reverts the "noindex" part of the original commit.
using noindex made it imposible to link to a specific property.
The original warnings do not pose an issue so until a proper solution is
found I am reverting this commit.
This reverts commit 953c232db3
The file subversion is no longer used in the Python API or user interface,
and is now internal to Blender.
User interface, Python API and file I/O metadata now use more consistent
formatting for version numbers. Official releases use "2.83.0", "2.83.1",
and releases under development use "2.90.0 Alpha", "2.90.0 Beta".
Some Python add-ons may need to lower the Blender version in bl_info to
(2, 83, 0) or (2, 90, 0) if they used a subversion number higher than 0.

When running with debug enabled ('-d' argument),
warnings are printed for add-ons which are not yet updated.
Reminder to name things based on what they do,
not the technologies they use :)
Blender can crash while rendering, when scene data is changed from within
a `frame_change_pre` or `frame_change_post` callback function. This results
in bug reports like T60094, T67627, and T73530. Until this is properly
resolved, this limitation should be documented.
No functional changes.
We still had a few deprecated assignements of `bpy.props.xxx` to class
members in our API documentation and one of our py tests. Annotations
are to be used now.
Also remove the section about `register_module` utils, this has been
removed in 2.8.
Fix T71877: Python API overview sample code warning: class MyMaterialProps contains a property which should be an annotation!
Fix T71876: Python API overview references old bpy.utils.register_module function
Some types were documented in bpy.types aren't accessible there.
For now, disable documenting types from add-ons and some types from
bl_operators, bl_ui... since these are mostly for internal use.
We need to handle beta stage in a specific way, since it's no longer
master, but not yet 'real' rc/release stage...
For now, only point to version dir of the API doc, but no need to create
any symlink (that way, 'current' remain pointing to 2.80 release, while
'2.81' is no longer a symlink to 'master', but its own actual doc).
This reverts commit 20b2acf336, reversing
changes made to f185cc0ca5.
Merges should only go form the release branch to master. For backporting
commits, use cherry-pick.
Python3.7 is still fairly recent, not all distro use it as system python
yet, fallback to code compatible up to py3.5.
Also, often distro builds of Blender do not have the buildinfo, in that
case fallback to `SOURCE_DATE_EPOCH` envvar, and as last resort to
current time, as in orig patch D5756 (we still use blender builddate
when available).
Issues raised in recent own rBcd5c70630318.
It makes much more sense to use the build timestamp of the Blender
binary used to generate that manpage, than the current time.
As a bonus, when Blender building makes use of the SOURCE_DATE_EPOCH envvar
(through CMake, since previous commit), this also propagate automatically
to that man page.
Inspired by D5756 by Bernhard M. Wiedemann (@bmwiedemann), thanks.
`object` is the superclass of all objects. Old-style code could still be
using `class SomeClass(object)` and assigning something else to `object`
could have unexpected results.
This is now also documented in the
[Python style guide](https://wiki.blender.org/wiki/Style_Guide/Python)
on the wiki.

We can not access ensured-to-be-evaluated dependency graph from the
render API: some of it is running from within evaluation which makes
it possible for engines to access list of evaluated IDs.
Solved by passing dependency graph to viewport functions, similar to
the final render functions.
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.

NOTE: I've included changes to FBX exporter, and those are addressing
report T63689.
NOTE: All the enabled-by-default addons are to be ported still, but
first want to have agreement on this part of changes.
NOTE: Also need to work on documentation for Python API, but, again,
better be done after having agreement on this work.
