Description

Currently we support the insertion of TIFF and JPEG into a PDF, but not PNG. We can pass a BufferedImage, but this one will be JPEG compressed which is not a good thing for graphics with sharp edges. I suggest that we support PNG as well. It is possible because the Flate Filter supports both directions.

My implementation (coming in a few minutes) is just an RGB based start that begs for improvement.
