With the property JEditorPane.W3C_LENGTH_UNITS we can control if the fonts
should show with the screen resolution with the mystic default size (for
example a pixel is larger as a point). The calculation is in class
CSS$LengthUnit. For server side printing we need a const resolution of 96
DPI.
 
Todo this we want overide some methods but this is not possible because the
classes and methods are not public. The keys of attributes in
javax.swing.text.html.CSS.Attribute.* are public. But the related values are
not public.
 
RFE:
1.) Make the inner classes and methods from javax.swing.text.html.CSS
 public.
2.) Add an Attribute for the ScreenResolution that we can print with a
    constant resolution independent of the screen on server.
