/**
 * Retrieves theme installer pages from the WordPress.org Themes API.
 *
 * It is possible for a theme to override the Themes API result with three
 * filters. Assume this is for themes, which can extend on the Theme Info to
 * offer more choices. This is very powerful and must be used with care, when
 * overriding the filters.
 *
 * The first filter, {@see 'themes_api_args'}, is for the args and gives the action
 * as the second parameter. The hook for {@see 'themes_api_args'} must ensure that
 * an object is returned.
 *
 * The second filter, {@see 'themes_api'}, allows a plugin to override the WordPress.org
 * Theme API entirely. If `$action` is 'query_themes', 'theme_information', or 'feature_list',
 * an object MUST be passed. If `$action` is 'hot_tags', an array should be passed.
 *
 * Finally, the third filter, {@see 'themes_api_result'}, makes it possible to filter the
 * response object or array, depending on the `$action` type.
 *
 * Supported arguments per action:
 *
 * | Argument Name      | 'query_themes' | 'theme_information' | 'hot_tags' | 'feature_list'   |
