integers are %i and floats %f (which defaults to %.6f)
we really need at least 6 digits precision with graphics; for colors 3
digits is ok

so your document is 99% graphics then?
actually there are a few other optimizations i want to do (cm and such)
but this is also related to literal processing in general (i need that
for runtime generated fonts because (esp when we randomize too) one
easilly get megs of inline fontdata

neglectable i guess, dealing with color spaces and such takes way more
runtime

i'm not going to change this so i fear that you will end up with your
own low-res version
