no, just interpolate to only 1/2 as many samples horizontally as luminance 
and duplicate uv for every 2nd pixel

ok, ill keep it, although i did mean something different, appearently iam not 
too good at explaining it :(
but the idea with no uv interpolation is nice too,but i think we wont gain 
that much with it compared to the 1/2 interpolation, as we still need to 
reorder the samples
