but i just noticed ,that the svn doesn't have background.png anymore.
That is a pity ,because due to it's alpha channel it would allow for more expressive custom themes.
Also I need to correct myself in the previous post.
The file background.png actually does NOT get rendered onto screen in the latest release of wagic, my bad.
I mixed it up with the 0.8 release probably, because i clearly remember that file being part of the design at some point in time...
