Exception created in RGUI.exe (PR#1748)

[ripley@stats.ox.ac.uk]

point 1 is user error: there are only fonts 1 to 5 documented anywhere
for this device.  pdf() in R-devel has been Holtman-proofed.

point 2 is also user error: the text falls on the boundary of the plot
region.  The PS device can clip partial text, whereas the PDF device
cannot.  Use xpd=TRUE if you want to plot on the edge of the region.
