title: Is there a limit of pixiJS canvas size
body: <p><strong>Problem</strong></p>
  
  <p>Hi everyone i got a problem with my canvas generated with pixiJS library. I need to create a tool which allow to users to custom and improve image quality with brigtness, contrast, sharping etc. The probleme is that I work with big pictures (7000x3500px) and the picture is distorted after putting effects. In my company i got the problem with just a MAC. In others devices it works well.</p>
  
  <p><strong>Example of simple code</strong></p>
  
  <pre><code>var canvas2 = document.createElement( "canvas" );
  canvas2.width   = 7000;
  canvas2.height  = 3500;
  
  var image2 = new Image();
  image2.src = "img2.jpg";
  
  var ctx2 = canvas2.getContext( "2d" );
  
  image2.addEventListener( "load", function() {
      ctx2.drawImage( image2, 0, 0 );
  
      var app         = new PIXI.Application();
      var texture     = new PIXI.Texture.fromCanvas( canvas2 );
      var sprite      = new PIXI.Sprite( texture );
      app.stage.addChild( sprite );
  
      var color = new PIXI.filters.AdjustmentFilter();
      sprite.filters = [color];
      color.red = 1.5;
      var exp = app.renderer.plugins.extract.canvas( sprite )
  
      console.log( exp.toDataURL( "image/jpeg" ) );
  } );
  </code></pre>
  
  <p><strong>Results</strong></p>
  
  <p>I changed width and height.</p>
  
  <p>Firstly (800pc / 400px) : good image.</p>
  
  <p>Secondly (7000px/3500px) : distorted image</p>
