-// Displays and hide pop-up menus.
-// Pop-ups are displayed when left-clicking on an edition icon of a link.
-// The HTML corresponding tags are supposed being the following:
-//
-// <a href="popupname"><img src="{path}icon.ed..." .../></a>
-//
-// Any other HTML construct will be ignored.
-//
-// Pop-ups can be used on a web page including java applets.
-// If a pop-up hides an applet, this latter must be hidden when displaying the pop-up - as a limitation,
-// the applet is supposed entirely hidden by the pop-up.
-// By convention:
-// - such pop-up must be named "toolpop" (<div id="toolpop"...></div><a href="toolpop">...</a>),
-// - the applet must be named "perform" (<applet id="perform"...></applet>).
