Re: [NTG-context] metafun / patterns
Sorry for the noise, my fault: Thunderbird replaced some semicolon
combinations with emojis, so they were missing when I copied and pasted
them in a source file.

Those first two pages appear 20x20mm and blank.
Page 3 and 4 show patterns instead.

[NTG-context] metafun / patterns
Hi,
As I'm still in metafun (and svg) mode I decided to support patterns
(that are already supported at the tex end) also in metafun. As there
has never been demands I suppose it's not that interesting but it sort
of fits in.
There are some tricky aspectx involved so the interface might evolve a
bit (some more control options) but here are some examples anyway:
