[Semyon Sadetsky]

Hello,

Please review fix for JDK10:
bug: https://bugs.openjdk.java.net/browse/JDK-8148619

webrev: http://cr.openjdk.java.net/~ssadetsky/8148619/webrev.00/

The algorithm selecting the best resolution variant of the 
BaseMultiResolutionImage was updated to be insensitive to the order of 
image variants in the initially provided array.

The BaseMultiResolutionImage specification was updated correspondingly.
