Comment:
Reference counting is needed because the BView is not the sole owner of
the tip, and since showing/hiding it works asynchronously via messaging.
The idea was that you need to subclass BToolTip if you want to have tool
tips that change while they are shown - this is because you could
otherwise not prevent the tip view from flickering, ie. you would need to
remove its current view, and add the new one.
In other words, changing the BToolTip is usually not what you should do,
if you are just displaying text anyway. If you are using the "const char*"
version of SetToolTip(), it should actually change the text on screen
directly.
If you manage to change the views without flicker, I wouldn't mind
allowing to change the BToolTip object that is currently being shown on
the fly.
Hope that counts as enlightening :-)
