Specifies whether the graphic inside a Tab is rotated or not, such that it is always upright, or rotated in the same way as the Tab text is.
By default rotateGraphic is set to false, to represent the fact that
the graphic isn't rotated, resulting in it always appearing upright. If
rotateGraphic is set to
true, the graphic will rotate such that it
rotates with the tab text.
