Add intensity slider to all color modes. Replace raw mode by linear mode, which uses linear color space.
When color is overbright, automatically switch hex text to script text. Allow executing expression in script text field to set color. Add the "script" icon to the default theme.
Remove an unused `VBoxContainer`.
Remove 3 unused children from grid (Label, Slider, SpinBox).
Ignore sample input when old color is not displayed.
Fix current color overbright position.
This adds binds for GraphEdit/GraphElement/GraphNode, which were
skipped before due to a rework. This also adds binds for Window,
which was skipped before due to a complicated code organization.
Also adds theme cache entries/direct cache access to a few places
that previously missed it. Some theme properties are now exposed
to other classes via friendships or public getters for convenience.
This removes all string-based theme access from scene/ classes.
With the 4.x-introduction of Windows the previous method for
color picking was no longer working.
This PR uses the following approach to reintroduce color-picking.
When the Color-Picking-Button is pressed, a quasi-screenshot of the
Window-content is created and displayed in a new Popup-Window.
This new Window allows selecting colors by Mouse-Click.
A Preview of the targeted Color is also displayed.
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".
