commit 494f565506013015d9ce4a3010eb3b211557d70f
Author: Noel Grandin <noel.gran...@collabora.co.uk>
Date: Fri Mar 16 10:37:12 2018 +0200
don't bother dithering for 256bit displays
which surely are a minority by now
Also drop the GetColorCount() method on OutputDevice and clean up the
remaining call sites to use GetBitCount()
