PDF output problem for a very specific case of shading (pending, needing fixing)
MdC code like m##//
won't render correctly in PDF output, with "gray" shading (you should get a shaded owl, and you get a gray square).
This code is made with a owl sign, with a shading sign from the "shading symbol" menu over it.
The problem is that in the PDF output, I avoid transparency (for preserving CMYK colours), and the gray square is drawn over the owl.
Note that the other shading systems, quadrant based or sign based, don't have this problem.
I will fix this problem when possible.
