Really? Do you have any evidence for this? In that case we might want to use
Vitaliys original patch which just changed the precision of the printed
float, since the patches I just sent break this ability. Henri and I
considered them as theoretical, since the HLSL compiler or shader author
would have removed those codepaths already
