Please review the fix for JDK 10.
The test runs with D3D and OpenGL both. The issue is with the OpenGL run as there aee some visual artifacts in image when the HiDPI scale is set to non-integer value like 2.5.
The issue is due to precision error. In WGLSurfaceData.java, the width and height is calculated by multiplying the width and height with scale. But the ceil function was being used instead of round. It should be using round as at most of the places, the round function is being used.
Also changed the test to run at uiScale of 2.5 to catch any further errors.
