Element: textstyle.font
Element: textstyle.fontfont
The font associated with textstyle. This can be a scalable or fixed font, although some graphic primitives require scalable font textstyles only. If no font is defined, a null value is recorded, and a default scalable font is used at draw time.
The font member may be redefined but must be the same style (i.e. scalable or fixed) as the font it replaces.
