Parameter

Parameter	Description
base	the base font which should be shrunk (not modified)
text	the string to fit within the given width
desiredWidth	the maximum possible width of the text, in pixels
getMetrics	a Graphics object which should be used to obtain FontMetrics for the given font

Return

a Font identical to base except possibly with a different font size as above
