add left & right to TooltipPosition

[SPSpisoft]

Please add the option to specify left and right to TooltipPosition. We have a widget that covers the entire height, and cannot use the top or bottom option to display the Tooltip.

Yes We need it for the widget with the height of device, because the tooltips disappear outside
