title: Haskell : Gloss error when trying to render a text
body: <p>I am trying to run this example: 
  <a href="https://raw.githubusercontent.com/elisehuard/game-in-haskell/master/src/Shapes.hs" rel="nofollow noreferrer">https://raw.githubusercontent.com/elisehuard/game-in-haskell/master/src/Shapes.hs</a></p>
  
  <p>But I get the error "freeglut  ERROR:  Function  called without first calling 'glutInit'." </p>
  
  <p>I managed to isolate the problem to line 39 :  "Color (bright magenta) $ translate 0 (-100) $ scale 0.2 0.2 $ text "Boo!""</p>
  
  <p>when I change it to : "Color (bright magenta) $ translate 0 (-100) $ scale 0.2 0.2 $ blank</p>
  
  <p>It's working fine.</p>
  
  <p>I am working on linux mint 19; Gloss version 1.13.0.1; gloss-rendering 1.13.0.2.</p>

  <p>Isn't the local Graphic branch supposed to shadow the existing one? It seems that it tries to replace it in full. </p>
