Did you remember to use always_sample off on the reading pass? Also, from
my experience, it is best to make sure you have the same nearest_count,
error_bound and recursion_limit. If you want it even faster, try reducing
count on the second pass: I found that 1/10 of the count on the first pass,
renders very quick without losing much quality.
BTW, I'm just testing this new load/save mechanism, and I'm missing a way
to know within the SDL if I'm loading or saving, to automatically adapt
textures and other details... anyone knows if this is possible?
