[Oberon] Aos Oberon and PNG

[edgar at edgarschwarz.de]

Hi all,
I modified AosPNGImages.Mod for Oberon and made a es.PNGImages.Mod.
So if you download "http://webdav.ethz.ch/no/es.PNGImages.Mod" and add some
entries to Oberon.Text (Have a look at the beginning of the file) you will
be able to open PNG in Aos Oberon and
"http://www.edgar-schwarz.de/cgi-bin/moin/SwOberon"
But be aware that they are upside down. Interesting feature :-)
Shouldn't be hard to fix but not so important for this evening.

Cheers, Edgar
