public class PatchFontMetrics

extends java.awt.FontMetrics

PatchFontMetrics wraps around a FontMetrics to correct some glaring errors that screw up pages laid out using FontMetrics! The main problems I've encountered were with heights. Except for the maxAdvance (which I dont understand what it's for), the other parameters have appeared to be reasonable. I've patched up the heights more or less heuristically; the big danger is that on some platform without such a correlation between pixels & points this may be worse than the original problem!
