Easy-to-use cross-browser tooltips.
Just include the script at the beginning of the section, and invoke
Tip('Tooltip text') from the desired HTML onmouseover eventhandlers,
and UnTip(), usually from the onmouseout eventhandlers, to hide the tip.
No container DIV required.
By default, width and height of tooltips are automatically adapted to content.
Is even capable of dynamically converting arbitrary HTML elements to tooltips
by calling TagToTip('ID_of_HTML_element_to_be_converted') instead of Tip(),
which means you can put important, search-engine-relevant stuff into tooltips.
Appearance & behaviour of tooltips can be individually configured
via commands passed to Tip() or TagToTip().

var tt_Debug = false // false or true - recommended: false once you release your page to the public
var tt_Enabled = true // Allows to (temporarily) suppress tooltips, e.g. by providing the user with a button that sets this global variable to false
var TagsToTip = true // false or true - if true, HTML elements to be converted to tooltips via TagToTip() are automatically hidden;
// if false, you should hide those HTML elements yourself
// For each of the following config variables there exists a command, which is
// just the variablename in uppercase, to be passed to Tip() or TagToTip() to
// configure tooltips individually. Individual commands override global
// configuration. Order of commands is arbitrary.
// Example: onmouseover="Tip('Tooltip text', LEFT, true, BGCOLOR, '#FF9900', FADEIN, 400)"
config. Above = false // false or true - tooltip above mousepointer
config. BgColor = '#E2E7FF' // Background colour (HTML colour value, in quotes)

config. BorderColor = '#dcdcdc'
config. BorderStyle = 'solid' // Any permitted CSS value, but I recommend 'solid', 'dotted' or 'dashed'
config. BorderWidth = 1
config. CenterMouse = false // false or true - center the tip horizontally below (or above) the mousepointer
config. ClickClose = false // false or true - close tooltip if the user clicks somewhere
config. ClickSticky = false // false or true - make tooltip sticky if user left-clicks on the hovered element while the tooltip is active
config. CloseBtn = false // false or true - closebutton in titlebar
config. CloseBtnColors = ['#990000', '#FFFFFF', '#DD3333', '#FFFFFF'] // [Background, text, hovered background, hovered text] - use empty strings '' to inherit title colours
config. CloseBtnText = ' X ' // Close button text (may also be an image tag)
config. CopyContent = true // When converting a HTML element to a tooltip, copy only the element's content, rather than converting the element by its own
config. Delay = 200 // Time span in ms until tooltip shows up
config. Duration = 0 // Time span in ms after which the tooltip disappears; 0 for infinite duration, < 0 for delay in ms _after_ the onmouseout until the tooltip disappears
config. FadeIn = 0 // Fade-in duration in ms, e.g. 400; 0 for no animation
config. FadeOut = 0
config. FadeInterval = 30 // Duration of each fade step in ms (recommended: 30) - shorter is smoother but causes more CPU-load
config. Fix = null // Fixated position - x- an y-oordinates in brackets, e.g. [210, 480], or null for no fixation
config. FollowMouse = true // false or true - tooltip follows the mouse

config. JumpHorz = false // false or true - jump horizontally to other side of mouse if tooltip would extend past clientarea boundary
config. JumpVert = true // false or true - jump vertically "
config. Left = false // false or true - tooltip on the left of the mouse
config. OffsetX = 14 // Horizontal offset of left-top corner from mousepointer
config. OffsetY = 8 // Vertical offset
config. Opacity = 100 // Integer between 0 and 100 - opacity of tooltip in percent
config. Padding = 2 // Spacing between border and content
config. Shadow = false // false or true
config. ShadowColor = '#C0C0C0'
config. ShadowWidth = 5
config. Sticky = false // false or true - fixate tip, ie. don't follow the mouse and don't hide on mouseout
config. TextAlign = 'left' // 'left', 'right' or 'justify'
config. Title = '' // Default title text applied to all tips (no default title: empty string '')
config. TitleAlign = 'left' // 'left' or 'right' - text alignment inside the title bar
config. TitleBgColor = '' // If empty string '', BorderColor will be used
config. TitleFontColor = '#FFFFFF' // Color of title text - if '', BgColor (of tooltip body) will be used
config. TitleFontFace = '' // If '' use FontFace (boldified)
