*
* Do NOT use this method in your code. This method will be removed as soon

*
* This is functionally very similar to DefaultHtmlFragmentRenderer::render()

*
* - drupal_prepare_page() and hook_page_build() cannot be invoked on the
* maintenance and install pages, since possibly enabled page layout/block
* modules would replace the main page content with configured region
* content.
* - This function composes a complete page render array including a page
* template theme suggestion (as opposed to the main page content only).
* - The render cache and cache tags is skipped.
*
* @param array|string $main
* A render array or string containing the main page content.
* @param string $title
* (optional) The page title.
* @param string $theme
* (optional) The theme hook to use for rendering the page. Defaults to
* 'maintenance'. The given value will be appended with '_page' to compose
* the #theme property for #type 'page' currently; e.g., 'maintenance'
* becomes 'maintenance_page'. Ultimately this parameter will be converted
* into a page template theme suggestion; i.e., 'page__$theme'.
* @param array $regions
* (optional) Additional region content to add to the page. The given array
* is added to the page render array, so this parameter may also be used to
* pass e.g. the #show_messages property for #type 'page'.
*
* @return string
