R: How can I change the aspect ratio of letters in a plot?

I want to plot letters, but I want to be able to plot e.g. a tall 'A' and a short 'A' both with the exact same width, but with different heights. In other words: How do I control the aspect ratio of letters in a plot?

Take a look at the source code to seqLogo, which is now part of bioconductor, I think. It draws a sequence logo from polygon calls, where each residue is a polygon drawn at a particular origin with a particular height and width. The aspect ratio is controlled by specifying the desired height and width.
