+Although by specification stemv values can be in principle floats/reals,
+pdftoepdf.cc/pdftex expects ints, and used getInt. Now, getInt in
+poppler breaks out if the value is not a real integer, but a float, while
+the getInt function in xpdf returns the (int)f instead.
+This patch uses round to obtain the closes value in case it is a float.
