Hi there,
I forward my change to this list, to show in detail what I have
in mind how to separate layouts. Just checkout hg tip, it's
quite simple to grasp.
config.mk has to be edited to define all .c files which contain
layout specific things, config.h has to be edited to include the
layout-specific header files (I refer to hg tip).
There is incmaster in tile.h again...
Regards,
Anselm
