++/**
++ * @test
++ * @run main InternationalFontsRendering
++ * @author Pavel Tisnovsky
++ *
++ * @summary This test check if all required fonts are properly installed and configured.
++ *
++ * This regression test checks if all required fonts are properly installed and
++ * that .src.properties font configuration is correct. The test is based on
++ * rendering certain characters from selected code pages into BufferedImage.
++ *
++ * When the font does not exists or font configuration is broken, only empty
++ * rectangle is rendered instead of the selected character shape. This rectangle
++ * is filtered and then the destination image is tested whether it is empty
++ * (=white).
++ *
++ * If test images with rendered characters needs to be created use following flag:
++ * -create-images
++ *
++ * regression for bug: https://bugzilla.redhat.com/show_bug.cgi?id=643674
++ * (Bug 643674 Misconfigured Path for Asian Font)
