Follow-up on displaying graphs etc

Hi

Just a quick follow-up on the recent thread about displaying images eg
graphs generated by other libraries such as gnuplot, scruffy, rmagick
etc.

The upcoming 1.9.6 release of wxRuby will support loading images from
arbitrary IO-like objects such as Files, Sockets and StringIO. Hopefully
this will be easier and more direct than messing around with writing to
and reading from Tempfiles.

cheers
