RINGWORLD2: Laser diffusion field doesn't look quite right

Reported by: eriktorbjorn Owned by: dreammaster
Priority: normal Component: Engine: TsAGE
Version: Keywords:
Cc: Game: Return to Ringworld


English CD version of the game

In the original, it looks like there's some kind of transparency effect or similar on the laser diffusion field. In ScummVM, it's a uniform dark gray.

Comparing the two screenshots, I also noticed that colours seem slightly darker in ScummVM (I've seen similar in games where the original doesn't use even 8 bits per colour, but I haven't checked if that's what's going on here) and that there's a dark line at the top of the scene in ScummVM. The latter is probably the only thing worth looking into.

The problem seems to be in Scene600::Smoke::getFrame(). Transparency isn't taken into account when copying the pixels
