Show a tooltip window displaying TEXT.
Text larger than `x-max-tooltip-size' is clipped.
If the alist in `tooltip-frame-parameters' includes `left' and `top'
parameters, they determine the x and y position where the tooltip
is displayed. Otherwise, the tooltip pops at offsets specified by
`tooltip-x-offset' and `tooltip-y-offset' from the current mouse
position.
Optional second arg USE-ECHO-AREA non-nil means to show tooltip
in echo area.
