#6 Finalizing Red-Hat port

[Dikhoff]

New layer model seems to have eliminating the threading
bug. Almost works correctly now. Two outstanding
actions needed:

1. convert all code to unix-type (dos2unix)
2. Loading 'arial' truetype font should be conditional
to windows platform. Other platforms shouls use default
font.

All in all a major achievement on the portability front :-)
