Right now, it is:
-O0: normal conversion (default)
-O1: convert polygons to bitmaps, text to text (-s poly2bitmap)
-O2: convert everything to bitmap (-s bitmap)
I'm thinking about shifting -O1 to -O2 however, so
that -O1 is --flatten, so we would have:
-O0: normal conversion
-O1: normal conversion + --flatten (reduce clippings)
-O2: convert polygons to bitmaps, text to text
-O3: convert everything to bitmap
Hope this shift won't cause confusion.
Right now, however, -O1 and -s poly2bitmap is equivalent.

That's true. That's because the implementation got improved (generates
less bitmaps than the Dec2007 snapshot). If I get around to it, I'll
optimize the conversion speed. (It's possible to speed it up by factor
3-4)
