Clean up lint.
Remove trailing whitespace.
Fix tab/space inconsistency (use spaces everywhere)
Add a global enable/disable for tooltips to be shown.
Merge branch 'global-enable-disable'
Fix sizing when class name changes content dimensions
Removed whitespaces
make position rely on getBBox (svg/vrml) when available
Got rid of the mentions about the `images` directory, since images were removed in 5ce79f52854e1f27dbe0067d4f70591fc8433101.
Adding SVG support.
Add a method for passing in separate east and north margins
Add theme functionality to have multiply styles for tipsy elements
Use 0 if we don't get anything back from offset{Width,Height}
Do not call getTitle() if tip is disabled. This way tip can be disabled to avoid unhandled exceptions raised by user-supplied functions. It's a minor optimization, too.
Use getBBox() for size and position of SVG objects
Fix for IE svg items, which like over/out instead
Handle super-long unbroken strings

If your text is long and doesn't have spaces, the tooltip just cut it off 
and the right margin would overflow. Now it wraps anyway which looks a bit 
cleaner.
Add extra class before calculating tooltip position
Add basic ARIA support
Made ARIA optional and attribute removed during hide as it is invalid once the tooltip is gone
