[9] Review request for 8132123 MultiResolutionCachedImage unnecessarily creates base image to get its size

[Alexander Scherbatiy]

Hello,
Could you review the fix:
  bug: https://bugs.openjdk.java.net/browse/JDK-8132123
  webrev: http://cr.openjdk.java.net/~alexsch/8132123/webrev.00

  The baseImageWidth/Height and Image.UndefinedProperty are returned to 
not trigger base image creation in the MultiResolutionCachedImage.


Thanks,
Alexandr.
