Has anyone got any good ideas on the following - I have thought up some
ways of doing what I want but I wondered if there was anything faster!

Consider two pixels side by side - when I draw an image I want to set
the red component of one pixel and the green component of the other,
without affecting the other colour components of the two pixels - this
is repeated over the whole image.

I have a solution which requires writing the image twice, once for red,
once for green, but was wondering if there were anyways of doing it with
one write?

I suspect there isn't!

Performer relevance - I want to do this with a Performer simulation, so
speed is very important, I'm already at 30Hz and I really don't want to
go lower.

I look forward to hearing any imaginative suggestions.

Graham Jones.
