Full-page screenshot on Selenium v>=3.4.0?

Question

Selenium developers have decided to discontinue the full-page screenshot feature: https://github.com/SeleniumHQ/selenium/issues/3912

What is the code necessary going forward, to emulate this feature in the application test scripts?

I tried to downgrade to Selenium 3.3.1, but there's some dependency on the driver and/or browser version which is not forward-compatible.

Solution found in an obscure open-source library:

pom.xml

    <dependency>
        <groupId>ru.yandex.qatools.ashot</groupId>
        <artifactId>ashot</artifactId>
        <version>1.5.4</version>
    </dependency>

SomeJavaTest.java

private void screenshot(File out) throws IOException, InterruptedException, AWTException {

    final Screenshot screenshot = new AShot()
            .shootingStrategy(ShootingStrategies.viewportPasting(100))
            .takeScreenshot(driver);

    final BufferedImage image = screenshot.getImage();
    ImageIO.write(image, "PNG", out);

}
