I notice that the font-rendering is not good in this PNG file.  I
suspect that the FreeType + fontconfig backend is not being used
in this case.  To get the benefit of the change in gp_cairo.c, the
pango and cairo libraries must be built with support for
fontconfig, and the DLLs for freetype, fontconfig and expat must
all be present.  DLLs that work in this respect can be found at

http://www.gtk.org/download-windows.html

For testing purposes, it would be easy to put a debugging print
statement into gp-cairo.c following line 703, to see if the
FreeType backend is in fact activated.
