* Declare `__toString()` as public.
* Use parent() and error() internally, rather than the properties.
* Add and correct inline documentation throughout.
* Attempt to clarify that display() is superior to get().
see #20546, see #20103.

* ['Template Files'] and ['Stylesheet Files'] need to return files from the parent theme as well.
* Don't strip links from the Author header. Some themes rely on the previous behavior, such as to link multiple authors (Sandbox, for example.) Don't restore links to the Name, that's just a bad idea.
* Ensure we are always passing around arrays in get_files/scandir.
* Better inline doc for wp_get_themes() arguments.
* Introduce a 'force' flag for search_theme_directories() to re-scan, rather than return the cache. We will use this to re-build the theme_roots transient in get_theme_roots(), but it is more helpful for unit tests. Since search_theme_directories() is cached, don't cache again in wp_get_themes(). (Again benefits testing.)
* Handle duplicate theme names in the old get_themes() when two themes match (and neither are a default theme, which is already handled). wp_get_themes() will consider both names to be the same; this is just for back compat since get_themes() is keyed by name.
* Include an old array key in wp_broken_themes().

Allow a default theme within a directory of wp-content/themes (e.g. 'somedir/twentyeleven') to be identified as a default theme.

* 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 #19816.
* 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 #6007 (not fixed yet, but will be easy now). For headers, fixes#15858.
* 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#11214.
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()
