[hidpi] sun/java2d/SunGraphics2D/DrawImageBilinear.java test fails

This fails with the following error on all three GDI, OpenGL and D3D at HiDPI scale of 1.25 or 1.75 with exceptions similar to following
Failed. Execution failed: `main' threw exception: java.lang.RuntimeException: Test failed at x=10 y=10 (expected=0xffff0000 actual=0xffff6060)

This bug is found while working on JDK-8159142, but the reason is different. So needs to fixed separately. A new test case should be written which checks the Frame bounds, Graphics clip and Robot screen capture API, to confirm that they are using same level of rounding
