[etoys-dev] Category not showing up in viewer

[karl ramberg]

But these are really for doing color filters for sketches and  images so we

It's possible to do all sorts of color changing etc. and it's pretty fast
because they are run with the scratch plugin.

I'm not sure if we should use the standard color category or another.
