correct "width" to "height" in "updateTooltipPosition"

Shouldn't:

+        if (pos.y > ($(document).height() - 2 * $("#flotTip").width() - this.tooltipOptions.shifts.y)) {
be:

+        if (pos.y > ($(document).height() - 2 * $("#flotTip").height() - this.tooltipOptions.shifts.y)) {[/pre>

?  i.e. when fixing the y position it should be with respect to the tooltip height, not width.
