Don't look at Cg, it's going away.

Ideally I'd like to have a 16bit channel support in Qt. The future of 
KImageEffect looks as follows right now:
a) scrap it,
b) create OpenGL SL to C compiler and finish SL support in Mesa,
c) create image manipulation library where /all/ algorithms are 
implemented with SL. 
d) build a simple graph library on top of it. So you can mix and match 
the algorithms from C as filters. 

If the hardware supports fragment shaders, we're getting hardware 
accelerated image manipulation library of the bat, if it doesn't we're 
getting software fallbacks for free. It'd be one codebase that unifies 
it all.


Winners compare their achievments to their goals, 
losers compare theirs to that of others.
