Subject: Keep the start/end spinbuttons as GtkWidget
X-Git-Url: http://git.tdb.fi/?p=ext%2Fsubsurface.git;a=commitdiff_plain;h=8e6bdc4f94eec68ab88cfc031c2358acd0a34b3b

Keep the start/end spinbuttons as GtkWidget

For graying things out, we want a widget, not a spinbutton.  Although
I'm sure we could just cast things back and forth.  But let's be
consistent with what we do, and only ever cast from GtkWidget to
GtkSpinButton, and have the same logic as for the "o2" widget that also
needs to be explicitly enabled.
