* A note on this class: What we really want is a FontMetrics2D object (i.e.
* font metrics with float precision). Unfortunately, it doesn't seem
* the JDK provides this. However, looking at the JDK code, it appears the
* metrics contained in the LineMetrics are actually the metrics of the font, not
* the metrics of the line (and empirically strings of "X" and "j" return the same
* value for getAscent()). So... for now we use LineMetrics for font metrics.
