/***
 * @internal
 * This action shows the list of selectable themes to user.
 *
 * [Notice]
 * XOOPS Cube Legacy can have many themes with different render-systems.
 * The render-system should not control how to change the themes.
 * Because this action can't list up themes of other render-systems.
 * The action to change themes should be in Legacy. And, each render-system
 * should send theme information through delegate-mechanism.
 * Therefore, this class is a test for that. We may move this action from
 * LegacyRender module. If you want to check the concept of this strategy, see
 * ThemeSelect preload in Legacy module.
