Custom header: Use add_theme_support('custom-header', $args) instead of add_custom_image_header(). Deprecates all use of constants.
* HEADER_TEXTCOLOR is now (string) 'default-text-color'.
* NO_HEADER_TEXT is nowi ! (bool) 'header-text'.
* HEADER_IMAGE_WIDTH (and _HEIGHT) are now (int) 'width' and 'height'.
* HEADER_IMAGE is now (string) 'default-image'.
* The 3.4 arguments 'suggested-width' and 'suggested-height' are now just 'width' and 'height' (they are "suggested" when flex-width and flex-height are set).
* Callback arguments for add_custom_image_header() can now be passed to add_theme_support().
Custom background: Use add_theme_support('custom-background, $args) instead of add_custom_background(). Deprecates all use of constants.
* BACKGROUND_COLOR is now (string) 'default-color'.
* BACKGROUND_IMAGE is now (string) 'default-image'.
* Callback arguments for add_custom_background() can now be passed to add_theme_support().
Inheritance: add_theme_support() arguments for custom headers and custom backgrounds is a first-one-wins situation. This is not an unusual paradigm for theming as a child theme (which is included first) overrides a parent theme.
* Once an argument is explicitly set, it cannot be overridden. You must hook in earlier and set it first.
* Any argument that is not explicitly set before WP is loaded will inherit the default value for that argument.
* It is therefore possible for a child theme to pass minimal arguments as long as the parent theme specifies others that may be necessary.
* Allows for a child theme to alter callbacks for <head> and preview (previously, calling add_custom_image_header more than once broke things).
* The just-in-time bits ensure that arguments fall back to default values, that the values of all constants are considered (such as one defined after an old add_custom_image_header call), and that all constants are defined (so as to be backwards compatible).
get_theme_support(): Introduce new second argument, which headers and backgrounds leverage to return an argument. current_theme_supports() already supported checking the truthiness of the argument.
* For example, get_theme_support( 'custom-header', 'width' ) will return the width specified during registration.
* If you had wanted the default image, use get_theme_support( 'custom-header', 'default-image' ) instead of HEADER_IMAGE.
Deprecate remove_custom_image_header(), remove_custom_background(). Use remove_theme_support('custom-header'), 'custom-background'.
Deprecate short-lived custom-header-uploads internal support; this is now (bool) 'uploads' for add_theme_support().
New 3.4 functions renamed or removed: Rename get_current_header_data() to get_custom_header(). Remove get_header_image_width() and _height() in favor of get_custom_header()->width and height.

* ['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().

Since search_theme_directories() now generates this and leverages this as a cache, convert absolute to relative on cache storage, and relative to absolute on cache retrieval.

* 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()

* Update it to use PHP5 scandir().
* Don't scan individual theme dirs -- we only need to check for style.css. (Solid performance gains.)
* Improve and simplify branching.
* Introduce wp_cache_themes_persistently filter to enable persistent caching of the return value, based on the theme_roots transient.

Make get_theme_root_uri() tolerate an absolute path for a theme root. It will now make an attempt to find a corresponding URL for absolute paths as well.
see #17597.

These functions were changed in [15641] to avoid any calculations when only one theme directory is registered. However, the short-circuit ended up being relative to WP_CONTENT_DIR, rather than absolute. This broke situations where theme roots are outside the content directory (technically allowed), and made return values inconsistent, as when multiple roots were registered, absolute paths were always returned.
fixes#17597. see #20103. see #14911.
