Tiling/scaling should probably be configurable.

Okay, sounds good. I thought about corner/edge images but it seemed to
be too much work for the benefit it gives us. On the other hand you
really do want to have nice corners. :-)

A separate theme file sounds great. Does that mean that the <options>
part in the layout file is obsolete? It looks like mostly theme stuff
goes in there. We should also define the colors for the font there.
Should the theme be selected in the keyboard layout or should there be
a command line option or both? I'd go with having a default theme
setting and optionally specifying one in the keyboard layout.

Okay, great. Thanks for the pointers.
