Wordpress/wp-settings.php
Andrew Nacin 53a209a4ee Introduce WP_Theme, wp_get_themes(), and wp_get_theme() to replace get_themes(), get_theme(), get_theme_data(), current_theme_info(), and others.
* Getters and Helpers: Introduces a series of methods to allow for easy generation of headers for display, and other theme metadata, including page templates.
 * Screenshots: Handles support for multiple screenshots. (see # Additional screenshots must be PNG and start with screenshot-2.png, and be sequential to be counted. see .
 * Error Handling: Broken themes have a WP_Error object attached to them.
 * Caching: Introduces a wp_cache_themes_persistently filter (also in [20020]) to enable persistent caching of all filesystem and sanitization operations normally handled by WP_Theme (and formerly get_file_data() and get_themes()). Themes are cached individually and across five different cache keys for different data pieces.
 * Compatibility: A WP_Theme object is backwards compatible with a theme's array formerly returned by get_themes() and get_theme(), and an stdClass object formerly returned by current_theme_info().
 * i18n/L10n: Theme headers are now localizable with proper Text Domain and Domain Path headers, like plugins. (Language packs may remove the requirement for headers.) For page templates, see  (not fixed yet, but will be easy now). For headers, fixes .
 * PHP and CSS files: New methods that fetch a list of theme files (for the theme editor) only on demand, rather than only loading them into memory. fixes .

Functions deprecated:
 * get_themes(), get_allowed_themes() and get_broken_themes() -- use wp_get_themes()
 * get_theme() and current_theme_info() -- use wp_get_theme()
 * get_site_allowed_themes() -- use WP_Theme::get_allowed_on_network()
 * wpmu_get_blog_allowedthemes() -- use WP_theme::get_allowed_on_site()
