Documentation
X offset, in pixels, for the display of tooltips.
The offset is the distance between the X position of the mouse and the left border of the tooltip window. It must be chosen so that the tooltip window doesn't contain the mouse when it pops up, or it may interfere with clicking where you wish.
If tooltip-frame-parameters includes the left parameter,
the value of tooltip-x-offset is ignored.
