Lighting Artifacts in Beta 3

I'm getting some strange artifacts with the advanced lighting that didn't show up in the earlier betas.

I'm seeing it here too... i'll post the fix as soon as i figure out what caused it.

Whats causing it is that in beta 3 we needed to be able to blend into the prepass buffers for terrain rendering. To make this work on some cards (mostly Geforces) we need to use GFXFormatR16G16B16A16F for the prepass texture.
It seems that its something about encoding depth into the float format that is causing this, but i haven't nailed the solution just yet.
