Functions
Functions that are not part of a class:

__construct( $args = array()   X-Ref
Constructor.

param: array $args {

doing_ajax( $action = null )   X-Ref
Return true if it's an Ajax request.

param: string|null $action Whether the supplied Ajax action is being run.
return: bool True if it's an Ajax request, false otherwise.

wp_die( $ajax_message, $message = null )   X-Ref
Custom wp_die wrapper. Returns either the standard message for UI
or the Ajax message.

param: mixed $ajax_message Ajax return
param: mixed $message UI message

wp_die_handler()   X-Ref
Return the Ajax wp_die() handler if it's a customized request.

setup_theme()   X-Ref

establish_loaded_changeset()   X-Ref
Establish the loaded changeset.

This method runs right at after_setup_theme and applies the 'customize_changeset_branching' filter to determine
whether concurrent changesets are allowed. Then if the Customizer is not initialized with a `changeset_uuid` param,
this method will determine which UUID should be used. If changeset branching is disabled, then the most saved
changeset will be loaded by default. Otherwise, if there are no existing saved changesets or if changeset branching is
enabled, then a new UUID will be generated.


after_setup_theme()   X-Ref
Callback to validate a theme once it is loaded


start_previewing_theme()   X-Ref
If the theme to be previewed isn't the active theme, add filter callbacks
to swap it out at runtime.

validate_setting_values( $setting_values, $options = array()   X-Ref
Validates setting values.

already null since they will be skipped anyway. Sanitization is applied

trash_changeset_post( $post )   X-Ref
Trash or delete a changeset post.

The following re-formulates the logic from `wp_trash_post()` as done in
`wp_publish_post()`. The reason for bypassing `wp_trash_post()` is that it
will mutate the the `post_content` and the `post_name` when they should be
untouched.

param: int|WP_Post $post The changeset post.
return: mixed A WP_Post object for the trashed post or an empty value on failure.

handle_changeset_trash_request()   X-Ref
Handle request to trash a changeset.


grant_edit_post_capability_for_changeset( $caps, $cap, $user_id, $args )   X-Ref
Re-map 'edit_post' meta cap for a customize_changeset post to be the same as 'customize' maps.

There is essentially a "meta meta" cap in play here, where 'edit_post' meta cap maps to
the 'customize' meta cap which then maps to 'edit_theme_options'. This is currently
required in core for `wp_create_post_autosave()` because it will call
`_wp_translate_postdata()` which in turn will check if a user can 'edit_post', but the
the caps for the customize_changeset post type are all mapping to the meta capability.
This should be able to be removed once #40922 is addressed in core.

param: int      $user_id The user ID.

param: WP_Post $post             The post object.

_publish_changeset_values( $changeset_post_id )   X-Ref

This will the values contained in a changeset, even changesets that do not
correspond to current manager instance. This is called by
`_wp_customize_publish_changeset()` when a customize_changeset post is
transitioned to the `publish` status. As such, this method should not be
called directly and instead `wp_publish_post()` should be used.

Please note that if the settings in the changeset are for a non-activated
theme, the theme must first be switched to (via `switch_theme()`) before
invoking this method.

param: int $changeset_post_id ID for customize_changeset post. Defaults to the changeset for the current manager instance.

_render_custom_logo_partial()   X-Ref
Callback for rendering the custom logo, used in the custom_logo partial.

This method exists because the partial object and context data are passed
into a partial's render_callback so we cannot use get_custom_logo() as
the render_callback directly since it expects a blog ID as the first
argument. When WP no longer supports PHP 5.3, this method can be removed
in favor of an anonymous function.

return: string Custom logo.
