This commit adds the default theme context, which replaces
the need to manually check the project and the default theme
all the time; simplifies related code.
It also adds framework for custom theme contexts, to be used
by the editor. Custom contexts can be attached to any node,
and not necessarily a GUI/Window node. Contexts do no break
theme inheritance and only define which global themes a node
uses as a fallback.
Contexts propagate NOTIFICATION_THEME_CHANGED when one of their
global themes changes. This ensures that global themes act just
like themes assigned to individual nodes and can be previewed
live in the editor.
Negative values are not valid and will always cause lightmap bleeding
to occur.
This also improves the documentation for the `uv2_padding` property
in the class reference.
As many open source projects have started doing it, we're removing the
current year from the copyright notice, so that we don't need to bump
it every year.
It seems like only the first year of publication is technically
relevant for copyright notices, and even that seems to be something
that many companies stopped listing altogether (in a version controlled
codebase, the commits are a much better source of date of publication
than a hardcoded copyright statement).
We also now list Godot Engine contributors first as we're collectively
the current maintainers of the project, and we clarify that the
"exclusive" copyright of the co-founders covers the timespan before
opensourcing (their further contributions are included as part of Godot
Engine contributors).
Also fixed "cf." Frenchism - it's meant as "refer to / see".
Somehow I missed the failing CI report from trailing whitespace.
Fixed a couple typos found by codespell while at it, and misc
trailing semicolons in one of the files.
For `PROPERTY_HINT_ENUM` properties, enumerator names can be provided as
a comma separated list. There're a few properties that add leading
spaces to the names (e.g. `First, Second, Third`).
These spaces are included in the Inspector dropdown, which is
unexpected.
It's better to leave the surrounding spaces untouched because it could
be part of the resulting string value (the variable is a string enum).
And most other enum hints don't contain surrounding whitespaces.
This PR removes the spaces and documents this `PROPERTY_HINT_ENUM`
behavior.
Clean up and do fixes to hash functions and newly introduced murmur3 hashes in #61934
* Clean up usage of murmur3
* Fixed usages of binary murmur3 on floats (this is invalid)
* Changed DJB2 to use xor (which seems to be better)
