                * domTT_activate returns the id of the tip if it needs to be referenced externally
                * added domTT_isActive() to check for an activated tip, returns tip object if active
                * create domTT_true() function, which should be used to wrap domTT_activate for onmouseover

                * domTT_activate uses options from domTT_activate call to override predefined options
                * take off restriction for status of onmouseover and just let it happen as it will
                * caption now not used if empty, even if it is sticky (can externally close tip)
                * added 'contextmenu' event type alongside 'click' for auto changing delay to 0
                * if content is empty, bail on creating the tip (hmmm...still thinking on this)
                * Gecko always makes the tip 4px too wide, for some unknown reason (maybe gecko bug?)
                * bug in right edge detection (was giving the width the padding instead of taking away)
                * fixed bug in global onmousemove (wasn't passing event to function for mozilla)
                * fixed edge detection, which was not accounting for scroll offset
                * made function domTT_correctEdgeBleed() for edge bleeding (since I used it twice)
                * code cleanups, added docs and another example page

version 0.1.7 (2002/11/18):

                * domTT_close can be an object, hence an image for an 'X' for close

                * changed mouseover to mousemove for event on the tooltip (prevent artifact tooltips)
                * added delay as option (will use global if not passed in)
                * added status as an option, which will change the status bar text
                * eliminated collision detection delay when tip is already visible
                * 'sticky' option changed to 'type' and can be 'greasy' or 'sticky'
                * fixed some serious bugs in setTimout logic when destroying tips
                * created function domTT_show() for showing hidden tip (previously created)
