Hello.
Please review the fix for jdk 9.

The new blit was implemented: D3DGeneralTransformedBlit. Performance difference is 30 seconds vs 25 ms in the test from https://bugs.openjdk.java.net/browse/JDK-8029253 I cannot provide J2DBench results because it simply crash my video driver(before/after the fix) if d3d pipeline is enabled. I will take a look at it later.
