css: Add a workaround for gtk_widget_override_font()

The problem here is that the CSS machinery expects font sizes to be in
pixels, but gtk_widget_override_font() provides a value in point and the
CSS machinery has no ability to query the DPI and convert.

This patch changes the dconversion DPI we use from a hardcoded 96 to the
default screen's DPI, which should work better than before.
This will of course not listen to changes in the default screen's DPI,
but that shouldn't be a problem.

People who want to workaround this should use gtk_widget_override_font()
with a font that has an absolute size set via
pango_font_description_set_absolute_size (size * PANGO_SCALE *
                                          gdk_screen_get_resolution (screen));
