Saying that BICUBIC is expensive - i have found any noticeable performance impact when using this code. And it is not always the scale down that needs this hint - even scaling up of the icons when scaling factor is set to 125 or 175% gives much better result for icons that do not have the exact match in size for the said scaling. ------------- PR: https://git.openjdk.java.net/jdk/pull/7805
