Setting COLORS geomview vars where we make the
change in geomview.

Fixing typo pointed out to me privately.

Grouping Geomview menu items separately.

It's a multiline Tcl command, so you need \ before the linefeed.
This isn't the text in about.tcl !!

tidying up geomview color procedures.

Update all variable names now we have more that one geomview COLOR.
(Defined in init.tcl)

Minor improvements to setting body color.

First take on setting sphere color in Geomview.

Simple attempt to turn off map if it's no longer Earth.

Tidyup and supporting horizontal graticule on spherical,
a la cylindrical. Shaping vertical is just too hard.
