 \item[letterspace=$x$] 
 Adds $x/S$ space between letters in words, where $S$ is the font size.

+\item[embolden=$x$]
+Increase the envelope of each glyph by the set amount (this makes the letters look `more bold'). $x=0$ corresponds to no change; $x=1.5$ is a good default value.

+\item[extend=$x$]
+Stretch each glyph horizontally by a factor of $x$ (i.e., $x=1$ corresponds to no change).

+\item[slant=$x$]
+Slant each glyph by the set amount. $x=0$ corresponds to no change; $x=0.2$ is a good default value.
