Hi Michael,

Yes, I had noticed the differences in intensity, but I'd put it down to bad 
color tables on my part, and never really looked deep into it. Also, I 
assumed that I'd done something wrong while activating hardware MIP.

Maybe we (and other interested people) could pool in a little effort in 
getting the hardware MIP to work? I want it badly enough that I'm prepared to 
spend some free time developing it.

Regards,
