Well, it's not quite like that. To pull this off, you'd have to take everywhere
we set a color, and set it instead to its equivalent black and white value
(there's a formula that's traditionally used, although there's no "correct" way
to do it: Y = 0.3*R + 0.59*G + 0.11*B). You *might* be able to get away with
modifying the LLColor4 constructor to do this, but it's probably going to have
some surprising results when you assign a value and don't get the same value
back.
Next, you'd have to filter all of the textures so that all textures are first
converted to B&W before being used. That's also a troublesome task, and is
likely to be slow.
On certain graphics cards, you could try to convert all the pixel shaders to do
a B&W conversion for each pixel before rendering, but I don't know enough about
our system to know if that would catch all the useful cases or not.
I hope that helps, but I'm not particularly optimistic. :/
