title: How to set texture to automatically match with a change in window size by using same texture
body: <p>I made a small 2D game by using unity3D(5.0.2f1). I dragged in some textures to use as the background in a scene. It worked well in the Unity Editor, but not when I built and ran it in a different window size. It didn't look as what I had seen in Unity Editor.</p>
  
  <p>What should I do to change the texture size automatically when window size changes? Here is a screenshot of how the image looks in the editor and the build, as well as my build settings:</p>
