    Fixed save_to_buffer methods inside the gdk-pixbuf bindings
    
    The gdk-pixbuf bindings were using the wrong method definiton for the
    methods gdk_pixbuf_save_to_buffer and gdk_pixbuf_save_to_bufferv, which
    made them unusable. This commit introduces a -custom.vala file to fix
    this problem and create usable method signatures.
