the sig2pix hasn't changed much since (at least i don't think that 
performance has decreased)
i haven't done any profiling, but i think a lot of CPU-power is wasted 
while casting from float to int and back again, and when getting the 
luminance of the image to map to vertices.
performance isn't *that* bad, bit i thought it could be better.

i don't think that conversion to pixes and then to vertices is optimal.
