[Spice-devel] [PATCH spice-gtk 04/12] seamless-mode: Remove redundant function draw_seamless()

[Jakub Janků]

Background is already being drawn transparent in spice_cairo_draw_event()
in spice-widget-cairo.c by calling
    cairo_set_source_rgba(cr, 0, 0, 0, 0);
    cairo_fill(cr);
there's no need to draw it twice.
