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.
