Kent, I can confirm this issue - it was bad enough to make me convert
everything to jpgs and use jpg2swf, which does not have the problem.
If this can be fixed, that would be huge...

I'm testing the Windows version of png2swf to convert 32-bit PNG
avatars to SWF files for display in an OpenLaszlo application. The
only version of SWFTools that will create a clear SWF is 0.6.1. All
newer versions produce a fuzzy rendering in OpenLaszlo.
Using a swfdump tool, one difference I see is that all versions
after 0.6.1 are applying a -10,-10 twip (half a pixel) transform to
the bitmap whereas 0.6.1 does not. I think this is causing the image
to be smoothed when it should not be at 100% scale.
What is the purpose of this 10 twip transform? Below are the SWF
dumps for 0.6.1 and 0.9.0.
