Frame parameters used for tooltips.
If left or top parameters are included, they specify the absolute
position to pop up the tooltip.
Note that font and color parameters are ignored, and the attributes
of the tooltip face are used instead.
This variable was added, or its default value changed, in Emacs 26.1.
Probably introduced at or before Emacs version 23.1.
