// LinkDock - V 1.5
// By Brian Gosselin
// Release Info:
// V 1.0 - Initial release.
// V 1.1 - Minor code changes for magnification smoothness and accuracy.
// V 1.2 - Added option to include text under the links as they are hovered over.
//         Fixed a magnification bug when the page is too small to fit the whole menu.
// V 1.3 - Fixed a bug where you get script errors if you hover over an image before the
//         page finishes loading.
// V 1.4 - Added a tweak by RAJ to smoothen the entry into the menu.
// V 1.5 - Fixed mouse bug where the mouse wasn't tracking right when dock was wider than the
//         page and the page was scrolled to the right. 

// ENTER LINK ATTRIBUTES IN THE ARRAY BELOW; EACH LINE CONTAINS ALL THE
// PARAMETERS FOR ONE LINK. USE THE FOLLOWING FORMAT:
//   [ 'LINK_URL' , 'IMAGE_URL' , 'URL_TARGET', 'TEXT_UNDER_LINK' ]
// VALID VALUES FOR 'URL_TARGET' ARE:
//   '_blank'   (NEW WINDOW)
//   'name'     (THE NAME OF AN EXISTING WINDOW OR FRAME)
//   ''         (CURRENT PAGE)
// IF YOU DO NOT WANT TEXT DISPLAYED UNDER A LINK, SIMPLY USE AN EMPTY STRING AS THE PARAMETER FOR 'TEXT_UNDER_LINK'.
