Font rendering improvements with JDK8 b109

[Felix Bembrick]

I have noticed quite a significant improvement in the quality of font
rendering since JDK b109 on my Windows machine.  The text looks darker and
crisper and is now almost on par with the quality of fonts in something
like IE10.

What has changed?  Am I just imagining it (I don't think so!)?

N.B. The font rendering within Canvas or TextFlow still remains very poor
:-(
