What a text box draws with: its fill, its line and the font of its text.
Remarks
A chart's title, legend, axes, data labels and data table are text boxes: one
getStyle() answers how each looks, as range.getStyle() does for a cell. A part with no text,
such as a series or the plot area, answers an IShapeStyle; isITextBoxStyle tells them
apart.
The font reads what is drawn, stated or not; what the box does not state it takes from the text
around it. toJSON answers only what the box states.
