Working on - JDK-8090423 - [Font] Support Font Weights other than Bold and Regular, like Light

[Tom Schindl]

Hi Phil,

I haven't looked too deep into that but to the "only" problem I see is 
how the internal lookup tree is structured in "PrismFontFactory".

And yes you are right the OS/2-Table (there's even a comment in 
PrismFontFile mentionning usWeightClass) contains the necessary 
information, some mac-fonts use the header-segment so there one has to 
distinction but those font would be simply classified as BOLD(700).

I'll put that on my opensource working queue, to look a bit deeper into 
that and get back with a more in depth report (and probably questions).

The current in ability to use FontWeight is a real problem compared to 
WebUIs, and although there is a work around not using FontWeight in CSS 
it is very cumbersome.
