object -- a gtk-text-tag object
scale -- a double float with the font size as a scale factor

Accessor of the scale slot of the gtk-text-tag class.

Font size as a scale factor relative to the default font size. This properly adapts to theme changes etc. so is recommended. Pango predefines some scales such as the +pango-scale-x-large+ value.
