    StThemeNode: Fix the confusion between border and background
    
    In d66e7dd49 I got confused between border_texture and
    background_texture. The background_texture was being created as normal
    but in the one place that it gets drawn I accidentally made it use the
    border_material instead. This patch makes it create a
    background_material similar to the border_material and uses it to
    paint.
