OK, that's a good point, and I fully agree with it. It's only that I
would probably use something like that for really simple, short,
one-page documents, where I would be concerned about the speed I need
to come to a solution, not with the speed of document processing -
half a second more or less.

With the route tex -> .plt file -> gnuplot -> tex (metafun) ->
metapost (-> mpto or \sometxt) -> pdf, which I frequently use, the
situation is much much worse, but it's still acceptable. ConTeXt
became at least 10 times faster during the last three or four years.
(Or at least that's my impression.)

Thanks. I always use fill fullcircle for some reason. Perhaps I should
changle my habit :)
