[Fluxus] (hint-nozwrite)

[Dave Griffiths]

Hi all,

I've added (hint-nozwrite) which can sometimes alleviate transparency
problems. It disables writing to the z buffer for primitives it's set
on, which means things rendered after it and behind it will still show
through. 

There is no silver bullet for transparency though, I found this rather
nicely written page on the subject:
http://www.opengl.org/wiki/Transparency_Sorting

cheers,
