// left designate version of DOCJSLIB where first introduced:
// 3.1 fix a bug in findHighestZ (change () to [] for documentDivs)
// 3.0 docjslib_doThisCommandEveryIntervalMS (executes a command every
// inteval)
// 3.0 docjslib_getWindowWidth (gets the width of the browser's window,
// in pixels)
// 3.0 docjslib_getWindowHeight (gets the height of the window,
// in pixels)
// 3.0 docjslib_getPageScrollLeft (gets the width of the scrolled area,
// pixels)
// 3.0 docjslib_getPageScrollTop (get the height of the scrolled area,
// pixels)
// 1.0 docjslib_getSrc (gets the image's URL of a DHTML element, url)
// 1.0 docjslib_setSrc (sets the image's URL of a DHTML element)
// 2.0 docjslib_getWidth (gets the DHTML element's width, pixels)
// 2.0 docjslib_getVisibility (gets the DHTML element's visibility,
// true or false)
// 2.0 docjslib_setVisibility (sets the DHTML element's visibility,
// true or false)
// 2.0 docjslib_setPosFromLeft (sets the DHTML element's horiz.
// position, pixels from left)
// 3.0 docjslib_setPosFromTop (sets the DHTML element's vertical
// position, pixels from TOP)
// 2.0 docjslib_setZposition (set the Z position of the DHTML element,
// integer)
// 3.0 docjslib_findHighestZ (find the highest Z of all pages's DHTML
// elements)
// 1.0 docjslib_makeClickedImage (creates an image-based DHTML element
// with event handling capability)
// 3.0 docjslib_makeLinkedImage (creates an image-based DHTML element
// with a built-in link to a developer-specified location)
