This property allows you to stretch or condense the font to use for the text symbol. Font stretch is specified as a ratio: 1 is the default value and shows the font in the original dimensions. Anything less than 1 condenses the font, while a value above 1 stretches it.
This property applies to both point-based and line-based text.
define font-stretch : 0.9
