Agreed. THe user should be able to set the background color. I had tried
changing the default background for the simulavr dox but it didn't work
out to well.

There is a way to get png's to work as you like. Here's an example:

  http://entropymine.com/jason/testbed/pngtrans/

Here's a simple way to add transparency to a png:

  $ pngtopnm malloc-std.png > malloc-std.pnm
  $ pnmtopng malloc-std.pnm -transparent white > test.png

The test.png is also smaller than the original png (bonus fat! ;-)

I've attached the test.png. See if you browser can handle it. I think we
can live with this. Might need to run a check in configure that replaces
pngtopnm and pnmtopng with cat if they aren't available on a system.

How's that sound?

:) Sheesh.  Stupid licensing @$!#.  Everybody uses GIF...  I hope there
:) aren't more serious restrictions for using these servers.

I think it's more a case of stupid/gready patent holders than licensing.

I think this lays it out:

You might need to be logged in to read it.

Help that clearifies things some.
