Help me fix wxplot2d and wxplot3d on windows



I understand that wxplot2d and wxplot3d are broken in maxima-5.27 for 
windows.  I'd like to fix this and make a new release, but I need some 
help/guidance.

I think my move to gnuplot-4.6 broke something, and that this was fixed 
by a patch to share/draw/draw.lisp.

I don't see any difference between the 5.26 and 5.27 windows releases.  
The new draw.lisp file doesn't change things.  For both I get

(%i1) wxplot2d([x], [x,-5,5])$
?wxxmltag("C:/Documents and Settings/dabilling/maxout_1.png","img")

What should I see?  Are there any screenshots?  Could I have messed up a 
defaults file or something?
