Part of #134755 / #134766.
Adds options to the new Import Settings popover (added in 7a6beb65f4)
to toggle collection instancing for dragging in collections. It can be
toggled separately for linking and appending, since it's typical to use
instancing for linking, but not appending (current default, also with
this change).
Previously, toggling collection instancing was only possible via the
Adjust Last Operation panel but this wasn't obvious, many people were
not aware. Adding this option based on feedback by the Blender Studio.

Instead of requiring an image buffer to draw a bigger preview image
while dragging, allow passing an icon ID and draw that as preview. This
is also how we draw previews elsewhere. Use this for attaching the asset
previews to draggable buttons.
A small user visible change is that previews from the asset browser will
always draw at the default size (multiplied by the interface scale)
while dragging. Previously it used the same size as the asset browser
preview size, which I don't think was useful really. With small sizes
the preview while dragging got unnecessarily small too, with big sizes
it got in the way.
Needed for #131871.
There are operators in Blender that allow the user to import multiple
files at the same time, however this functionality is only implemented
when importing with blender's file browser, drag and drop files only
takes first selected file.
The patch adds support for drag and drop multiple files.
Notes:
* The files are filtered according to the extension of the first
selected file.
* Not all operators that import files support importing multiple files,
so they will still import one.
* Changes must be made to allow importers to read all file paths.
This will be used in upcoming drag & drop import.

It was already called that way in the UI, since it's referring to a
behavior, not a type. Update the code to match that. Note that this is
a BPY compatibility breaking change for 4.0.
Listing the "Blender Foundation" as copyright holder implied the Blender
Foundation holds copyright to files which may include work from many
developers.
While keeping copyright on headers makes sense for isolated libraries,
Blender's own code may be refactored or moved between files in a way
that makes the per file copyright holders less meaningful.
Copyright references to the "Blender Foundation" have been replaced with
"Blender Authors", with the exception of `./extern/` since these this
contains libraries which are more isolated, any changed to license
headers there can be handled on a case-by-case basis.
Some directories in `./intern/` have also been excluded:
- `./intern/cycles/` it's own `AUTHORS` file is planned.
- `./intern/opensubdiv/`.
An "AUTHORS" file has been added, using the chromium projects authors
file as a template.
Design task: #110784
Ref !110783.
Context is needed to import and instantiate assets correctly. Previously
the context was stored as "evil" pointer in the drag data. Since
77794b1a7b, context is passed to the dragging callbacks doing the asset
import, so the context doesn't need to be stored that way anymore and
can simply be passed to the import function.
`AssetHandle` is meant as temporary design and should be replaced by
`AssetRepresentation`. This moves us another step closer to that.
Rather than taking data from the volatile asset handle and storing that
in the drag data, store the (more persistent) asset representation there
and access data from it where needed.
A lot of files were missing copyright field in the header and
the Blender Foundation contributed to them in a sense of bug
fixing and general maintenance.
This change makes it explicit that those files are at least
partially copyrighted by the Blender Foundation.
Note that this does not make it so the Blender Foundation is
the only holder of the copyright in those files, and developers
who do not have a signed contract with the foundation still
hold the copyright as well.
Another aspect of this change is using SPDX format for the
header. We already used it for the license specification,
and now we state it for the copyright as well, following the
FAQ:
https://reuse.software/faq/
No behavior change intended.
Many file drag & drop handlers used the icon assigned for dragging to
determine what type of data is dragged. This is fragile, for example
changing an icon would break drag & drop (!). This happened a few times,
e.g. see 3788003cda. It's also causing problems with #104830, which
changes how file browser drag data is handled.
Instead use the file extension to determine the file type.
This reverts commit 19222627c6.
Something went wrong here, seems like this commit merged the main branch
into the release branch, which should never be done.
This reverts commit 68181c2560.
I merged 3.6 into 3.5 by mistake. Basically I had a PR against main,
then changed it in the last minute to be against 3.5 via the
web-interface unaware that I shouldn't do it without updating the
patch.
Original Pull Request: #104889
Note that the node group has its sockets names
translated, while the built-in nodes don't.
So we need to use data_ for the built-in nodes names,
and the sockets of the created node groups.
Pull Request #104889
Introduces a new `AssetRepresentation` type, as a runtime only container
to hold asset information. It is supposed to become _the_ main way to
represent and refer to assets in the asset system, see T87235. It can
store things like the asset name, asset traits, preview and other asset
metadata.
Technical documentation:
https://wiki.blender.org/wiki/Source/Architecture/Asset_System/Back_End#Asset_Representation.
By introducing a proper asset representation type, we do an important
step away from the previous, non-optimal representation of assets as
files in the file browser backend, and towards the asset system as
backend. It should replace the temporary & hacky `AssetHandle` design in
the near future. Note that the loading of asset data still happens
through the file browser backend, check the linked to Wiki page for more
information on that.
As a side-effect, asset metadata isn't stored in file browser file
entries when browsing with link/append anymore. Don't think this was
ever used, but scripts may have accessed this. Can be brought back if
there's a need for it.
We would first invoke the dragging, and then set the drag data (like the
ID or the dragged modifier), so the `wmDropBox.on_drag_start()` handler
wouldn't be able to access this. This broke dragging some IDs from the
Outliner, noticed in D15333.
It's now possible to first create/request drag data, extend it, and then
invoke the actual dragging. The normal function to start dragging
returns `void` now instead of `wmDrag *`, so the drag data can't easily
be modified after starting anymore.
Moves code for managing dragging data from buttons to a separate file.
This way all this closely related code is in one location, making it
easier to see how it all relates, and easier to find.
