FVWM: fvwm using "compatible" colors

Hello again,

As you know by now, I still have a X11R4 server. And I like to use fvwm
on this machine as well as on my Linux X11R6 at home. Therefore I think
it would be sensible to make "plain fvwm" runnable on all X11R{4,5,6,6.1}
platforms.

Yesterday, I sent out a list of "not compatible" colors. I re-checked
today (I always had wondered what the error messages from all the fvwm's
I use (1.24, 2.0.41, 2.0.42) meant:
    [FVWM][nocolor]: <<ERROR>> can't parse color slategrey
    fvwm: can't parse color slategrey
). Here's what I found:

1) "plain fvwm" has a built-in startup command
      ExecuteFunction("MenuStyle black grey slategrey fixed fvwm", ...)
    which references the (X11R5-and-above-only) color slategrey.
    The patch to use grey50 instead follows below.

2) system.fvwmrc uses (too) many different colors, two of which are
    completely unknown under X11R4: palevioletred and LightSkyBlue are
    candidates for replacement by a different "close" color from the set
    of named colors; The unnamed colors should be chosen from the set of
    named colors as well. Using Romano <romano_at_iet.unipi.it> Giannetti's
    "pixy" program, the following replacement table comes to mind (the
    (dist nnnn) tells you how "different" the replacement color is from
    the original color):
      #40a0c0 - sky blue (dist 169.387)
      #484048 - gray26 (dist 20.793)
      #554055 - violet (dist 31.169)
      #5f9ea0 - cadet blue (dist 1.973)
      #705070 - violet (dist 136.791)
      #908090 - gray52 (dist 117.541)
      #aa80aa - blue violet (dist 198.276)
      #cab3ca - thistle (dist 13.309)
      #cfcfcf - gray81 (dist 0.000)
      Black - black (dist 0.000)
      Green - green (dist 0.000)
      LightSkyBlue(X11R5)/#87cefa(X11R4) - sky blue (dist 278.405)
      MidnightBlue - midnight blue (dist 0.000)
      Yellow - yellow (dist 0.000)
      blue - blue (dist 0.000)
      grey40 - gray40 (dist 0.000)
      grey60 - gray60 (dist 0.000)
      maroon - maroon (dist 0.000)
      palevioletred(X11R5)/#db7093(X11R4)-medium violet red (dist 0.000)
      steelblue - steel blue (dist 0.000)
    (Well, I think I would use gray25/50/80 in place of 26/52/81...)
    THESE ARE NO 1:1 REPLACEMENTS! But they help new users on older
    platforms to initially use fvwm (without a private .fvwmrc, fvwm won't
    start correctly unless it has successfully loaded the basic menu colors).
    Using the derived sed script (X11R4.sed) below, and executing
        sed -f X11R4.sed new-system.fvwmrc.orig >new-system.fvwmrc
    we get the diffs below for an X11R4-capable system.fvwmrc.

    I do hope that these patches can help anybody out there who's still
    stuck on X11R4....

    Have fun,
        Martin
