/**
 * @file
 * Provide a javascript based dropbutton menu.
 *
 * An example are the edit/disable/delete links on the views listing page.
 *
 * The dropbutton menu will show up as a button with a clickable twisty pointer
 * to the right. When clicked the button will expand, showing the list of links.
 *
 * The dropbutton will stay open until either the user has moved the mouse
 * away from the box for > .5 seconds, or can be immediately closed by
 * clicking the twisty again. The code is smart enough that if the mouse
 * moves away and then back within the .5 second window, it will not
 * re-close.
 *
 * Multiple dropbuttons can be placed per page.
 *
 * If only one link is passed to the theme function, the function will render
 * a ctools-button with no twisty.  The twisty is only rendered when 2 or more
 * links are provided. The wrapping element will be classed with both
 * ctools-button and ctools-dropbutton when a dropbutton is rendered.
 *
 * If the user does not have javascript enabled, the link will not appear,
 * and instead by default the list of links will appear as a normal inline
 * list.
 *
 * The menu is minimally styled by default, and to make it look different
 * will require your own CSS. You can apply your own class to the
 * dropbutton to help style it.
 *
 * The twisty is rendered as a border on a widthless and heightless element.
 * There is no image for the twisty.
 * The color of the twisty is the color of the link by default. To adjust the
 * size of the twisty, adjust the border widths on .ctools-twisty. The adjust
 * the color of the twisty, assign a new color to the .ctools-button class or
 * assign a color to .ctools-twisty. You shouldn't need to adjust border-color.
 *
 * Use the theme() function to render dropbutton e.g.
 * theme('links__ctools_dropbutton', array()) where array contains a renderable
 * array of links.
