In the default situation (that is unless you have specified a value for
the wkPDFResolution resource, see below) the PDF driver sets its
internal
coordinate space limits to the intervals [900,14400] in X and
[3150,16650] in Y .
In order to generate your warnings you have to have generated an
internal
coordinate with an absolute value larger than 99999. This may or may
not
indicate a problem in your code, which is why this is only a
warning. The PDF
driver ignores such out of range coordinates and issues the
warnings. The X11
and PS drivers will let any coordinate pass through, but if they are
as far out
of range as the ones that produce the PDF warning, they will not be
seen on a plot.

However, these warnings *could* be triggered by your having set
wkPDFResolution to a value very much larger than its default of 1800,
like 13,000. Have you done this? It was not anticipated that anyone
would ever need that kind of resolution, but if this is needed, then we
should know about it so we can up the limits.
