Thanks for pointing that out. I will have a look into my code again.
I was (and actually I still am) confused by the different shading
methods provided by MetaFun. I admit that I never read the PDF
reference which means that I don't know the shading internals. I
experimented a little and came up with a working solution to add
some eye-candy to presentations.

I agree. Even Knuth designed his fonts as bitmaps (at least the
output is a bitmap). However, bitmaps always have a fixed size and
thus are not scalable.

ACK
And thanks for this nice module and especially for the well-written
documentation.
