    gskpango: Remove bounds rect
    
    We only need this to render shapes and trapezoids, i.e. only when
    falling back to cairo. Remove code to measure the layout and convert the
    ink_rect to a graphene_rect_t from gtk_snapshot_append_layout() and do
    it when drawing shapes and trapezoids instead.
