		Theme for controls.
	</brief_description>
	<description>
		A theme for skinning controls. Controls can be skinned individually, but for complex applications, it's more practical to just create a global theme that defines everything. This theme can be applied to any [Control]; the Control and its children will automatically use it.
		Theme resources can alternatively be loaded by writing them in a [code].theme[/code] file, see the documentation for more information.
