+                * Create a spinner element
+                *
+                * The argument is an object with options used to construct the spinner (see below).
+                *
+                * It is a good practice to keep a reference to the created spinner to be able to remove it
+                * later. Alternatively, one can use the 'id' option and #removeSpinner (but make sure to choose
+                * an id that's unlikely to cause conflicts, e.g. with extensions, gadgets or user scripts).
+                *
+                * CSS classes used:
+                *
+                * - .mw-spinner for every spinner
+                * - .mw-spinner-small / .mw-spinner-large for size
+                * - .mw-spinner-block / .mw-spinner-inline for display types
+                *
+                * Example:
+                *
+                *     // Create a large spinner reserving all available horizontal space.
+                *     var $spinner = $.createSpinner({ size: 'large', type: 'block' });
+                *     // Insert above page content.
+                *     $( '#mw-content-text' ).prepend( $spinner );
+                *
+                *     // Place a small inline spinner next to the "Save" button
+                *     var $spinner = $.createSpinner({ size: 'small', type: 'inline' });
+                *     // Alternatively, just `$.createSpinner();` as these are the default options.
+                *     $( '#wpSave' ).after( $spinner );
+                *
+                *     // The following two are equivalent:
+                *     $.createSpinner( 'magic' );
+                *     $.createSpinner({ id: 'magic' });

+                * - id: If given, spinner will be given an id of "mw-spinner-{id}"
+                * - size: 'small' (default) or 'large' for a 20-pixel or 32-pixel spinner
+                * - type: 'inline' (default) or 'block'. Inline creates an inline-block with width and
+                *   height equal to spinner size. Block is a block-level element with width 100%, height
+                *   equal to spinner size.
+                *
+                * If a string is given, it will be treated as the value of the 'id' option.
