Creates a PangoContext for the default GDK screen.

The context must be freed when you’re finished with it.

When using GTK+, normally you should use gtk_widget_get_pango_context() instead of this function, to get the appropriate context for the widget you intend to render text onto.

The newly created context will have the default font options (see

cairo_font_options_t) for the default screen; if these options

change it will not be updated. Using gtk_widget_get_pango_context() is more convenient if you want to keep a context around and track changes to the screen’s font rendering settings.
