[CM] CMN what happened to the non-Postscript backends?

[Ralf Mattes]

Hello list,

i just had a look at the cmn code (after a long time of just using it)
and saw that all of the non-Postscript backend stuff got removed. The
only thing I could find was a notice in the changelog:

 15-Mar: removed nxtcmn.c, sgicmn.c, xcmnw.c, cmn-mcl-utils.lisp,
cmn-mcl.lisp,
          cmn-excl.lisp, cmn-scroll.lisp.  Removed all FFI,
          quickdraw, and Braille stuff.


What was the reason for this? I wanted to look at the code to find out
how much work would be required to add other backends (Cairo/CLIM/PDF).

>From what understand looking at the current code all drawing operations
are functions and not generic methods - hard to specialize on the
backend.

 Cheers, Ralf Mattes
