border_width[3] = border_width[2] = border_width[1] = border_width[0];
colors[0] = colors[1] = colors[2] = colors[3] = *color;
+ gtk_snapshot_push_debug (snapshot, "CSS outline");
snapshot_border (snapshot,
gtk_css_boxes_get_outline_box (boxes),
border_width,
colors,
border_style);
+ gtk_snapshot_pop (snapshot);
