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.
No user visible changes expected. The feature is not exposed yet.
For the asset shelf (#102879), design is to use a paginated scrolling
style. That means, that any scrolling will always snap to a multiple of
the page size (the size used when pressing the Page Up/Down keys).
Together with strict region size snapping (implemented in the asset
shelf patch, #104831), this gives a clean scrolling experience where
partially visible rows are avoided (impossible even).
Introduces:
- `View2D.flag` value `V2D_SNAP_TO_PAGESIZE_Y`, which will cause any
scrolling to only use multiples of the page size.
- A custom page size via `View2D.page_size_y` for when the full region
size is not the appropriate page size value.
- API function `UI_view2d_offset_y_snap_to_closest_page()` to enforce
the snapping from outside View2D. The asset shelf uses this to keep
strict scrolling over DPI changes.
Pull Request: https://projects.blender.org/blender/blender/pulls/109154
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/
Code was exposing apparently internal functions to the public header, so
it could reuse it in other View2D files. Worse even, a struct was
defined twice in different source files and they would have to be kept
in sync, just because there is no shared header file.
Such internal header files are useful and don't really cause any harm.
