JDK-4138922 - Need to fully support multi-font
Description
Run the Java2D demo located in /usr/local/java/jdk1.2/solaris/demo/jfc/Java2D.  Take a look at the Memory Monitor and Performance Monitor canvases.

PerformanceMonitor strings are not positioned appropriately.  And the MemoryMonitor memory graph isn't positioned correctly.   Here's how the ascent's & descent's are determined :

MemoryMonitor :
   ascent = (int) offG.getFontMetrics(font).getAscent();
   descent = (int) offG.getFontMetrics(font).getDescent();

PerfomanceMonitor :
    ssH += (int) offG.getFontMetrics().getAscent()
                   + offG.getFontMetrics().getDescent();
