Function: tooltip-show

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.
