Each test in RegionBackgroundImageUITest makes several calls to `robot.getPixelColor()` on App thread. Due to this each test requires more than **60** seconds for execution.
Fix is to save a screen capture of Scene (on App thread) and then read pixel color from the screen capture(not on app thread). This reduces execution time of each test to less than **3** seconds.
Ideally with this fix(commit#1) all the tests should pass. All tests do pass on Windows and Linux but three tests fail on Mac, which used to pass without this change.
- RegionBackgroundImageUITest.unalignedImage
- RegionBackgroundFillUITest.testScenario2
- RegionBackgroundFillUITest.testScenario3
commit#2 solves the above problem. Solution is to fallback to test color again by reading it using `robot.getPixelColor()` on App thread when a test fails.
One test RegionBackgroundImageUITest.unalignedImage_Cover, fails only on Mac platform, before and after this fix.
It is reported as a new issue [JDK-8255679](https://bugs.openjdk.java.net/browse/JDK-8255679)
This is a test fix and affects only the tests that extend from `RegionUITestBase` test class and does not affect other tests.
Verified that `RegionBackgroundImageUITest` and `RegionBackgroundFillUITest` tests pass on all three platforms(except RegionBackgroundImageUITest.unalignedImage_Cover which fails on Mac).
