Subject: [PATCH] Fix uninitialized class name in dpi handling

Make the class in the XrmGetResource call be the same as the resource
name we are trying to retrieve, "Xft.dpi". Nowhere in the documentation
it is mentioned that the class name can be NULL so it is better to be
cautious and set it to a value that is unlikely to affect anything.
