First of all, the butterfly is looking better than ever
for me. It tints perfectly. I'll send you an example.
I'd have expected your PC to be very fast at this, because
the PC has built-in trancedental math functions in the CPU.
You have instructions for sin(), cos(), tan(), and so on.
Unlikely to be the problem, but...
One thing that may need to change for a PC is the place where
a double is compared against zero. Instead of this:
if(dst.sat>0)
You might be better off with:
if(dst.sat>0.00000001)
