[pygtk] SVG support on Windows?

The faq has been wrong for a long time, so I've removed that comment.
I have to admit, however, that getting things working might not be
obvious at first. For example, if you're using one of the "gtk+ bundles",
you don't have the pixbuf-loader responsible for loading svg files
(lib\gtk-2.0\2.10.0\loader\svg_loader.dll in your GTK+ installation).

Yep, the gtk+-bundle distribution does not contain that library and
it's dependencies out of the box. You'll need to install the following
into your GTK+ installation, all available from
http://ftp.gnome.org/pub/GNOME/binaries/win32/:
   svg-gdk-pixbuf-loader_2.26.2-1_win32.zip
   librsvg_2.26.2-1_win32.zip
   libcroco_0.6.2-1_wxin32.zip
   libxml2_2.7.7-1_win32.zip
   libgsf_1.14.17-1_win32.zip

Once you've done that, you'll need to execute the following commands:
   cd ?:\???\my-gtk+-installation\bin
   gdk-pixbuf-query-loaders.exe > ..\etc\gtk-2.0\gdk-pixbuf.loaders

That's about it,
Have fun,
Dieter
