sorry.. yes.. pngalpha. It worked the last time I used it although there
might be an issue with transparencies, although if its working you
should see a chessboard like pattern as a background when transparency
is turned on instead of white. 7.07 still may not provide you a good
preview even with those devices.

No because the print preview didnt support all the current features when
those docs were written. New ones are due for 1.2 and the Ghostscript
section has already been written.
