title: Scaling viewports in Godot 3
body: <p>New to Godot/GDScript and I am making a pixel art game. </p>
  
  <p>Low res graphics can easily be scaled up by scaling the viewport, however this affects the scale of all the nodes in the tree. Scaling down the viewport give the desirable crisp edges <strong>which cant be gotten from scaling up a sprite</strong> node (otherwise the pixel art blurs). The problem comes in when I want to display text or GUI elements over the game.</p>
  
  <p>I want to:</p>
  
  <ol>
  <li>render a tilemap and game sprites on a scaled up node/viewport e.g 120x100 scaled to the window size</li>
  <li>Render buttons and text (hud) at a consistent higher resolution on top of the game without scaling</li>
  </ol>
  
  <p>I have tried playing multiple viewports but I just dont have a grasp it yet.</p>
  
  <p>Any help in setting this up would be very appreciated!</p>
