[OpenJDK 2D-Dev] RFR: 8171303: sun/java2d/pipe/InterpolationQualityTest.java fails on Windows & Linux

[Sergey Bylokhov]

This the only test which was created to check different types of interpolation.
It checks the rendering to the VolatileImage and uses BufferedImage as a gold image.
But it does not take into account that rendering to the VolatileImage might be affected
by the HiDPI support.
