Can you confirm, that you see a correct sombrero plot when running

hf = figure ("visible", "off");
sombrero ();
__osmesa_print__ (hf, "foo.svg", "svg");

Can you upload the resulting foo.svg and add a link?
Do you have a good idea how to check if the generated image is as
expected and which is more robust?

Thank you in advance, Andy
