+This is a semi-automated test that displays vertical lines scrolling
+horizontally and asks user if tearing was observed.  Three variants are
+available:
+  * using uniform update.  This tests that glSwapInterval function performs as
+    expected.
+  * using full texture update.  This tests that CPU-GPU interaction is properly
+    synchronized in the driver.
+  * using pixmap to texture extension.  This tests that pixmap to texture
+    extension is properly synchronized.
