Bitmap fonts are not supported in PDF output, type check on label font to avoid mapserver setting errors

[unicoletti]

I am using Java mapscript from mapserver 4.4.0 to produce printable maps in PDF
format.
Whenever I try to print a map that uses bitmap fonts in a label an exception is
thrown in msDrawTextPDF because mapserver cannot find a suitable font. The
shp2pdf utility is able to ignore this error and the map gets drawn ok (except
for bitmap labels), but this is not possible in java mapscript because of the
exception handling code.

I am attaching a patch that checks for the font type and if it is bitmap it
simply returns without doing nothing.
Frankly I am not completely sure whether this is the best approach, but at least
it makes PDF output working as shp2pdf. Please note that this bug is related to
bug# 1128 and a more general solution should be devised in the future.
