[Magic-dev] Custom dstyle and cmap files

I rewrote the code to make what you're doing easier, but I have not
tested it exhaustively, so please let me know if it doesn't work as
I describe it.

The default dstyle and cmap files are "mos.24bit.dstyle" and
"mos.24bit.std.cmap" (or, if you prefer the OpenGL interface, like
I do, it's "mos.OpenGL.dstyle" and "mos.OpenGL.std.cmap").  The
initial "mos" is significant in that it corresponds directly to the
line "styletype mos" in the techfile.  Prior to changes I made to
version 7.3, changing the default would require intervention on the
command line.  What I did in version 7.3 was to hold off loading the
colormap and display style files until the techfile was being read,
at which point the proper filenames would be derived from the
"styletype" line in the "styles" section.

So (theoretically) what you want to do is to use your own unique
styletype, e.g.,

    styles
       styletype custom

corresponding to the files:

    custom.24bit.dstyle	  and
    custom.24bit.std.cmap

If you're polite, you'll also provide the "7bit" and "OpenGL" style
files and colormaps.  The load routines will look for the filenames
in "SysLibPath", which can be altered using the "path sys" command.
So instead of copying display and colormap files everywhere, you
should be able to put them in some obvious place, then copy only
a ".magicrc" file to every working directory, containing the "path
sys +<directory>" command, followed by "tech load <techfile> -noprompt".

And once again, let me know if you are not seeing the behavior as
advertised.
