Remove hadStyle, doesn't really say anymore that oldStyle. Write:

   oldStyle ? oldStyle->respectImageOrientation() : ...

  

[rwlbuis, 2015/06/15 17:21:51]

Done.

+    RespectImageOrientationEnum oldOrientation = hadStyle ? oldStyle->respectImageOrientation() : ComputedStyle::initialRespectImageOrientation();
+    if (style() && style()->respectImageOrientation() != oldOrientation)
+        intrinsicSizeChanged();

Devious and I love it.

Thanks :)
