This is the font used to draw text.
When setting a font you can specify a list of font names
separated with commas. The first available font will be used.
ImageGlue tries to cope with inexact matches by first looking for a
font with exactly the same name, second for a font which starts
with the font name provided and finally a font which contains the
font name provided
If you set a font using a list of Font names and then get the
value of the property the name of only the one font being used for
drawing text will be returned.
