/**
* Get an avatar for a BuddyPress object.
*
* Supports avatars for users, groups, and blogs by default, but can be
* extended to support custom components as well.
*
* This function gives precedence to locally-uploaded avatars. When a local
* avatar is not found, Gravatar is queried. To disable Gravatar fallbacks
* locally:
* add_filter( 'bp_core_fetch_avatar_no_grav', '__return_true' );
*
* @since 2.4.0 Added 'extra_attr', 'scheme', 'rating' and 'force_default' for $args.
* These are inherited from WordPress 4.2.0. See {@link get_avatar()}.
*
* @param array|string $args {
* An array of arguments. All arguments are technically optional; some
* will, if not provided, be auto-detected by bp_core_fetch_avatar(). This
* auto-detection is described more below, when discussing specific
* arguments.
*
* @type int|bool $item_id The numeric ID of the item for which you're requesting
* an avatar (eg, a user ID). If no 'item_id' is present,
* the function attempts to infer an ID from the 'object' + the
* current context: if 'object' is 'user' and the current page is a
* user page, 'item_id' will default to the displayed user ID; if
* 'group' and on a group page, to the current group ID; if 'blog',
* to the current blog's ID. If no 'item_id' can be determined in
* this way, the function returns false. Default: false.
* @type string $object The kind of object for which you're getting an
* avatar. BuddyPress natively supports three options: 'user',
* 'group', 'blog'; a plugin may register more. Default: 'user'.
* @type string $type When a new avatar is uploaded to BP, 'thumb' and
* 'full' versions are saved. This parameter specifies whether you'd
* like the 'full' or smaller 'thumb' avatar. Default: 'thumb'.
* @type string|bool $avatar_dir The name of the subdirectory where the
* requested avatar should be found. If no value is passed,
* 'avatar_dir' is inferred from 'object': 'user' becomes 'avatars',
* 'group' becomes 'group-avatars', 'blog' becomes 'blog-avatars'.
* Remember that this string denotes a subdirectory of BP's main
* avatar directory (usually based on {@link wp_upload_dir()}); it's a
* string like 'group-avatars' rather than the full directory path.
* Generally, it'll only be necessary to override the default value if
* storing avatars in a non-default location. Defaults to false
* (auto-detected).
* @type int|bool $width Requested avatar width. The unit is px. This value
* is used to build the 'width' attribute for the <img> element. If
* no value is passed, BP uses the global avatar width for this
* avatar type. Default: false (auto-detected).
* @type int|bool $height Requested avatar height. The unit is px. This
* value is used to build the 'height' attribute for the <img>
* element. If no value is passed, BP uses the global avatar height
* for this avatar type. Default: false (auto-detected).
* @type string $class The CSS class for the <img> element. Note that BP
* uses the 'avatar' class fairly extensively in its default styling,
* so if you plan to pass a custom value, consider appending it to
* 'avatar' (eg 'avatar foo') rather than replacing it altogether.
* Default: 'avatar'.
* @type string|bool $css_id The CSS id for the <img> element.
* Default: false.
* @type string $title The title attribute for the <img> element.
* Default: false.
* @type string $alt The alt attribute for the <img> element. In BP, this
* value is generally passed by the wrapper functions, where the data
* necessary for concatenating the string is at hand; see
* {@link bp_get_activity_avatar()} for an example. Default: ''.
* @type string|bool $email An email to use in Gravatar queries. Unless
* otherwise configured, BP uses Gravatar as a fallback for avatars
* that are not provided locally. Gravatar's API requires using a hash
* of the user's email address; this argument provides it. If not
* provided, the function will infer it: for users, by getting the
* user's email from the database, for groups/blogs, by concatenating
* "{$item_id}-{$object}@{bp_get_root_domain()}". The user query adds
* overhead, so it's recommended that wrapper functions provide a
* value for 'email' when querying user IDs. Default: false.
* @type bool $no_grav Whether to disable the default Gravatar fallback.
* By default, BP will fall back on Gravatar when it cannot find a
* local avatar. In some cases, this may be undesirable, in which
* case 'no_grav' should be set to true. To disable Gravatar
* fallbacks globally, see the 'bp_core_fetch_avatar_no_grav' filter.
* Default: false.
* @type bool $html Whether to return an <img> HTML element, vs a raw URL
* to an avatar. If false, <img>-specific arguments (like 'css_id')
* will be ignored. Default: true.
* @type string $extra_attr HTML attributes to insert in the IMG element. Not sanitized. Default: ''.
* @type string $scheme URL scheme to use. See set_url_scheme() for accepted values.
* Default null.
* @type string $rating What rating to display Gravatars for. Accepts 'G', 'PG', 'R', 'X'.
* Default is the value of the 'avatar_rating' option.
* @type bool $force_default Used when creating the Gravatar URL. Whether to force the default
* image regardless if the Gravatar exists. Default: false.
* }
*
* @return string Formatted HTML <img> element, or raw avatar URL based on $html arg.
