Theme for controls.

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 :ref:`Control<class_Control>`; the Control and its children will automatically use it.

Theme resources can alternatively be loaded by writing them in a ``.theme`` file, see the documentation for more information.

This adds ``theme_type`` as a suggested option for :ref:`Control.theme_type_variation<class_Control_property_theme_type_variation>` on a :ref:`Control<class_Control>` that is of the ``base_type`` class.

Variations can also be nested, i.e. ``base_type`` can be another variation. If a chain of variations ends with a ``base_type`` matching a class of a :ref:`Control<class_Control>`, the whole chain is going to be suggested as options.

**Note:** Suggestions only show up if this ``Theme`` is set as the project default theme. See :ref:`ProjectSettings.gui/theme/custom<class_ProjectSettings_property_gui/theme/custom>`.
