> Thanks to the fix in pdfbox-1442, I was able to get the ch14.pdf file 
> rendered. However the colors are incorrect. On page 13, the colors black and 
> red in the triangle are switched. (The same error is on page 1, 15 and 20 but 
> these take forever to render). I suspect a bug in the 
> shadingTinttransform.eval() function.
> I don't think its a bug in the shading interpolation code, because then there 
> would have been lots of visible triangles in the spheres and donuts on the 
> other pages where its not just a single triangle.
