commit bb074bdd2a30fd3b941be2683c905a99d330243a
Author: Peter Clifton <pcjc2@xxxxxxxxx>

    libgeda: Fix printing of colours.
    
    To avoid emitting a colour change for each object printed, libgeda caches
    the last colour it wrote into a postscript file, and doesn't emit a new
    colour change command when the next object is the same colour.
    
    Drawing of complex and text objects are wrapped by a "gsave" and "grestore"
    pair, which resets the postscript interpreter's current colour, so we need
    to restore our variable tracking the last drawn colour after these groups.
    
    Fixes mis-drawn colours noted by DJ on the geda-user list.
