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:
\starttext
\startMPpage[offset=1cm]
draw (fullcircle scaled 5cm shifted (0cm,0cm))
withpattern image (fill fullcircle scaled 1cm withcolor
"darkblue" ;)

;
draw (fullcircle scaled 5cm shifted (5cm,0cm))
withpattern image (fill fullcircle scaled 5mm withcolor
"darkred" ;)
