MultiResolutionToolkitImage should use the base image observer as a key for the observers cache.

I tried run the following code with JDK 1.8u25 build 17 using the following animated gifs on HiDPI display: http://designbuddy.com/wp-content/uploads/2013/02/david-ope-animation.gif http://www.freeallimages.com/wp-content/uploads/2014/09/animated-gif-images-2.gif http://media.giphy.com/media/YP3BAcE3bZMMU/giphy.gif I am not able to reproduce the problem. Could you send the animated gif where the issue is reproduced?

This issue need to be reproduced on Mac OS X using Quartz Debug simulation of HiDPI display. Tested this on regular display on OS X with JDK 8u20 and 8u40ea and is not reproducible. Passing this on for further evaluation.
