/**
 * @author Lindy Briggs
 *
 * AttributeCalculator is an interface, originally created by Lindy,
 * that allows us to get dynamic "attributes" (line widths, point widths, etc)
 * based on the *size* of the window that we're drawing into.  This allows for 
 * a more natural scaling process, and doesn't require us to write the same 
 * sizing code into each of our painters (or worse, have them all use a fixed 
 * style at all sizes).
