		Theme resource for styling/skinning [Control]s and [Window]s.
	</brief_description>
	<description>
		A theme resource is used for styling/skinning [Control] and [Window] nodes. While individual controls can be styled using their local theme overrides (see [method Control.add_theme_color_override]), theme resources allow you to store and apply the same settings between all controls sharing the same type (e.g. style all [Button]s the same). One theme resource can be used for the entire project, but you can also set a separate theme resource to a branch of control nodes. A theme resources assigned to a control node applies to the control itself, as well as all of its direct and indirect children (as long as a chain of controls is uninterrupted).
		Use [member ProjectSettings.gui/theme/custom] to set up a project-scope theme that will be available to every control in your project.
		Use [member Control.theme] of any control node to set up a theme that will be available to that control and all of its direct and indirect children.

				Creates or changes the value of the theme property of [param data_type] defined by [param name] and [param theme_type]. Use [method clear_theme_item] to remove the property.
				Fails if the [param value] type is not accepted by [param data_type].
				[b]Note:[/b] This method is analogous to calling the corresponding data type specific method, but can be used for more generalized logic.

			<description>
				Marks [param theme_type] as a variation of [param base_type].
				This adds [param theme_type] as a suggested option for [member Control.theme_type_variation] on a [Control] that is of the [param base_type] class.
				Variations can also be nested, i.e. [param base_type] can be another variation. If a chain of variations ends with a [param base_type] matching the class of the [Control], the whole chain is going to be suggested as options.
				[b]Note:[/b] Suggestions only show up if this theme resource is set as the project default theme. See [member ProjectSettings.gui/theme/custom].
