The old 3.0.x behavior was that the default facecolor was [0,1,0]. I 
presume that is the compatible behavior and so re-established that as 
the default with the attached patch. The demo in the help string then 
works correctly for the gnuplot CVS. But there appear to be some issue 
with colormap with gnuplot 4.2.4 and the x11 terminal in a multiplot 
environment.. I suppose I should try 4.2.5 and see if that works
