But the other \sometxt was indeed red - withcolor seems to work, but
only conditionally. And I have some weird examples of two texts one
after another. In some cases (if something else is drawn inbetween and
a color changed twice), then the second text will be black. But it's
quite unpredictable (that one might even be bug in my code, so I don't
want to complain before I have an example).
I while ago I also posted an interesting example with colored table
(withcolor colored only some of the cells), but that is alredy a very
And I can't afford to use \textext. It's was too slow (approximately
factor 10) and it runs out of TeX memmory after 10 or 12 plots on
A question for you or Hans: can please someone explain me in a few

understand exactly how TeX processes it (and metapost
shrinks/expands/shifts/colors) it inline.
