title: Draw standard NSImage inverted (white instead of black)
body: <p>I'm trying to draw a standard NSImage in white instead of black. The following works fine for drawing the image in black in the current NSGraphicsContext:</p>
  <pre><code>NSImage* image = [NSImage imageNamed:NSImageNameEnterFullScreenTemplate];
  [image drawInRect:r fromRect:NSZeroRect operation:NSCompositeSourceOver fraction:1.0];
  </code></pre>
  <p>I expected NSCompositeXOR to do the trick, but no. Do I need to go down the complicated [CIFilter filterWithName:@&quot;CIColorInvert&quot;] path? I feel like I must be missing something simple.</p>
