The attached changeset fixes this issue by computing the bounding box
of the text with the freetype renderer also when printing postscript.
This bounding box is used by the gl-render code to auto compute the
position of the axes labels.
Note - the on-screen fonts and the postscript fonts are not
necessarily identical, so the result might not look so good depending
on the available fonts on your system ....
