outline color, @Line width

Hi,

that's the best I can do to produce a paper heading,

@Diag
{
  # right and left lines
  blue @Color @Line from { -1.2c -0.7c } to { 10.0c -0.7c }
  blue @Color @Line from { 15.0c -0.7c } to { 17.0c -0.7c }
  # star
  blue @Color {
     @Line from { 8.8c -0.7c } to { 9.45c 0.2c }
     @Line from { 9.45c 0.2c } to { 9.6c -0.7c }
     @Line from { 9.6c -0.7c } to { 8.85c -0.15c }
     @Line from { 8.85c -0.15c } to { 9.85c -0.15c }
     @Line from { 9.85c -0.15c } to { 8.8c -0.7c }
  }
}

the 2 lines need to be thicker,
I could use outlinewidth with shape, but I can't draw a single line.

the star should definitly be a shape, but how can I define the outline color ?

thanks,
Jérémy
