title: Sprite Kit OS X: SKTexture size property is incorrect
body: <p>I'm testing a game on the OS X version of Sprite Kit, and find that some textures report their size incorrectly. I'm wondering if anyone else is seeing this problem and whether there is an explanation for it?</p>
  
  <p>Just to rule out any other issues before I report this as a bug. If this is a known bug, please say so.</p>
  
  <p>I'm loading this texture, it is 256x256 pixels in size:</p>
  
  <p><img src="https://i.stack.imgur.com/TaaCt.png" alt="enter image description here"></p>
  
  <p>When I log the SKTexture created from this image, then the SKTexture description gives me the correct size but the <code>size</code> property does not, it says the image is 204.8 x 204.8.</p>
  
  <pre><code>tex = &lt;SKTexture&gt; 'Tileset_GeometryB.png' (256 x 256)
  tex.size = {204.80000000000001, 204.80000000000001}  // Huh? WTF?!?
  tex.textureRect = {{0, 0}, {1, 1}}
  </code></pre>
  
  <p>I load the exact same texture using the same code on iOS Simulator and device - size property is always correct: 256x256.</p>
  
  <p>I also tried loading this texture before anything else just to avoid any possible side effects. Still the texture size is wrong.</p>
  
  <p>It is worth noting that this doesn't happen with all textures, but does happen on all 256x256 textures I load. A 128x256 texture reports its size correctly.</p>
  
  <p>I also did a clean build, and I'm testing on Mavericks (13A603) with Xcode 5.0.1 (5A2053).</p>
