 From the HTML5 <canvas> realm: I could really access to baseline 
positioning metrics.

As of this point, I'm not really able to set two differently sized fonts 
onto one shared baseline, in a run of text.

So, while we're talking about (and apparently shooting down) the idea of 
adding support for arbitrarily set baselines,
per CSS units, I'd like to point out that I could really use support for 
getting baseline calculations, much like getting other computed styles.
