[11u] RFR 8212226: SurfaceManager throws "Invalid Image variant" for MultiResolutionImage (Windows)

[Zhengyu Gu]

I would like to backport this to 11u for parity with Oracle 11.0.10-oracle.

The original patch does not apply cleanly. However, the only conflict is 
the copyright year of SunGraphics2D.java.
