theme_override properties have some special handling in EditorInspector. When caching documentation info for properties, the theme_item_name value (used only for theme_overrides) was not being cached, so it would only be included on first use. This meant that theme_override property tooltips would show up in the editor the first time a node was selected, but not again after selecting something else/reselecting. Added theme_item_name to caching to fix this.
Fixes#90395
This change introduces a new theme configuration struct to be
passed to the aforementioned routines to better control reuse
of styles and definitions in the generator.
Everything not passed and not explicitly shared is scoped so it
is not automatically accessible throughout the routine. This
should ensure that the decision to share styles is a conscious one.
In the future we will try to reduce the number of unique definitions
and share most of it. This PR is a stepping stone on this path.
This also puts the effort into separating redefinitions of
default theme items vs custom types introduced only by the editor.
In a few cases where editor-specific definitions need to reference
default definitions we simply fetch them from the theme. It's not
ideal and hides the dependency a bit, but hopefully these cases
will be abstracted properly in due time.
This change introduces a new EditorThemeManager class
to abstract theme generatio and its subroutines.
Logic related to EditorTheme, EditorColorMap, and editor
icons has been extracted into their respective files with
includes cleaned up.
All related files have been moved to a separate folder to
better scope them in the project. This includes relevant
generated files as well.
* Avoid concating strings manually for better i18n and easy l10n
* Use `vformat` when possible
* Use separate strings if the changing part is only a few hardcoded strings
* Don't put a period at the end of the name
