[Bf-committers] Renderer bugs

[Alexander Ewering]

Found several bugs in the current render code. This is what the scene
(check the particle grass, lens flares) looked like a few weeks ago:

Now it looks like this (unthreaded renderer):

Or this (threaded):

It seems like alpha values of particles behind each other don't add up
anymore. As you can see, the grass is semi-transparent, with the same
degree of transparency everywhere.

And the lensflare... it completely renders black.
