Log: Ton
- fix for specularity calculus. Because of new area lamps and new ray-shadow
some tests where moved around, causing specularity being calculared when
light actually shines behind a face.
Thanks inttr for the (horrible!) test scene that showed it.

Log:
- added clipping value for spothalo rendering. Unified render doesn't like
alpha>1.0, the 'threshold' calculation in vanillaRenderPipe.c then works
wrong... not sure if this should be fixed there.
- for now, the spothalo render function itself clips.
- again; thanks to horrible intrr test scene!

cheers
