vp := draw(x*y,x=0..1,y=0..1,style=="smooth")
write(vp, "t1", "postscript")
Then check "t1.VIEW/fricas3D.ps", you'll see only axes there.
After this patch, there will be black and white image. (this is
another bug.)
However, if you save the image by clicking buttons in
the control panel, you can have the black and white image.
As you can see that in process3d.c (responsible for the button
to save PS file):
redoSmooth = yes;
drawViewport(PSoption); /* draw picture in PS; create ps script
file */
