title: Cocos2d 2.1 AWTextureFilter blurring only part of texture
body: <p>I use Cocos2d 2.0 and AWTextureFilter. I need to blur texture. Here is my code:</p>
  
  <pre><code>//Create mutable texture
  CCTexture2DMutable *texture = [[CCTexture2DMutable alloc] initWithCGImage:[UIImage imageNamed:@"image.png"].CGImage resolutionType:kCCResolutionUnknown];
  
  //Apply blur to the mutable texture
  [AWTextureFilter blur:texture radius:10 rect:CGRectMake(0, 0, texture.contentSize.width, texture.contentSize.height)];
  
  //Create sprites to show the textures
  CCSprite *sprite = [CCSprite spriteWithTexture:texture];
  sprite.position = ccp(winSize.width/2, winSize.height/2);
  [layer addChild:sprite];
  </code></pre>
  
  <p>But in result I get sprite with only part of blurred (screenshot):
