[OpenJDK Rasterizer] RFR: Marlin renderer #2

[Laurent Bourgès]

Phil,

Do you have news from SQE team about the marlin patch ?

PS: I am working hard to implement properly few reconstruction filters (max
support 1.5 yet like tent, bell, gaussian 1/2...) and I expect it will
improve rendering quality with only a small performance penalty ! Of course
it should be used with a proper gamma correction...

Regards,
Laurent
