title: How to create SKTexture with rounded corners without using a mask
body: <p>I wish to create a simple node with facebook profile picture of a user, where the picture has rounded corners (or a complete circle). I create the node as follows:</p>
  
  <pre><code>SKNode *friend = [[SKNode alloc] init];
  
  SKTexture *texture = [SKTexture textureWithImage:user[@"fbProfilePicture"]];                
  SKSpriteNode *profilePic = [SKSpriteNode spriteNodeWithTexture:texture];
  
  [friend addChild:profilePic];
  </code></pre>
  
  <p>I could not find any proper documentation to create the image with rounded corners, other than using SKCropNode (which seems to be a bad workaround)</p>
