There's a high level irony in this thread, that I think is amusing. I
hope no one takes it personally, I'm a huge fan of Cairo, and indebted
to all of the work many people contribute.
The irony is that from a binding point of view, everything is in
double precision. Like I really need beyond 6 significant figures to
specify alpha composition. So we've got way more resolution than we
need (and it comes at a price from a call point of view, since it's
twice as much data to put on the bus, even if the op of manipulating
them is all done in 80bit land). But then when we get into these guts
issues, we're trying to figure out how to maximize the precision we
can express in a 32bit integer.
My Other Machine runs OSX. But then... so does this one.
