This is intentional, but I can see the problems it could create for a
large PS file, so it may be worth mentioning this in the
documentation. Basically, we leave it or the backend to do the
clipping to the view limits, and in postscript the total line path is
drawn and the clip rectangle is set. It would be difficult and
inefficient for us to do the clipping in the front end. Think about
pathological cases, for example, where the x,y center of a marker is
far outside the view limits, but the marker is very large so that some
of its vertices are inside the view limits.
Earlier versions of matplotlib had a data clipping feature where line
points outside the view box were removed before adding them to the
backend. But noone ever used it and it added complexity to the code
so I eventually deprecated it.
