Clarification: pcolormesh() must have a grid of coordinates (not
necessarially equally spaced).

As for pcolormesh() being able to handle anything that pcolor() can handle,
I have run into situations where that was not the case.  I don't remember
the details, though.  I think pcolorfast() operates like that (falling back
to pcolor() as a last resort).
