How to force a background color to fully opaque?

[zachernuk]

As we've discussed, a stereoscopically-rendered model probably shouldn't have a transparent background. Given that this is specified by CSS, what do we do with colors that are transparent? Is it better to ignore the alpha value and use the RGB as-is, or should it be multiplied down in some manner by the alpha?

(I think a monoscopic model does make sense to be rendered with a transparent background. I don't know the right way to square that.)
