+// This is a test harness for running javascript tests in the browser.
+// The only identifier exposed by this harness is WebGLTestHarnessModule.
+//
+// To use it make an HTML page with an iframe. Then call the harness like this
+//
+//    function reportResults(type, msg, success) {
+//      ...
+//      return true;
+//    }
+//
+//    var fileListURL = '00_test_list.txt';
+//    var testHarness = new WebGLTestHarnessModule.TestHarness(
+//        iframe,
+//        fileListURL,
+//        reportResults,
+//        options);
+//
+// The harness will load the fileListURL and parse it for the URLs, one URL
+// per line preceded by options, see below. URLs should be on the same domain
+// and at the  same folder level or below the main html file.  If any URL ends
+// in .txt it will be parsed as well so you can nest .txt files. URLs inside a
+// .txt file should be relative to that text file.
+//
+// During startup, for each page found the reportFunction will be called with
+// WebGLTestHarnessModule.TestHarness.reportType.ADD_PAGE and msg will be
+// the URL of the test.
+//
+// Each test is required to call testHarness.reportResults. This is most easily
+// accomplished by storing that value on the main window with
+//
+//     window.webglTestHarness = testHarness
+//
+// and then adding these to functions to your tests.
+//
+//     function reportTestResultsToHarness(success, msg) {
+//       if (window.parent.webglTestHarness) {
+//         window.parent.webglTestHarness.reportResults(success, msg);
+//       }
+//     }
+//
+//     function notifyFinishedToHarness() {
+//       if (window.parent.webglTestHarness) {
+//         window.parent.webglTestHarness.notifyFinished();
+//       }
+//     }
+//
+// This way your tests will still run without the harness and you can use
+// any testing framework you want.
+//
+// Each test should call reportTestResultsToHarness with true for success if it
+// succeeded and false if it fail followed and any message it wants to
+// associate with the test. If your testing framework supports checking for
+// timeout you can call it with success equal to undefined in that case.
+//
+// To run the tests, call testHarness.runTests(options);
+//
+// For each test run, before the page is loaded the reportFunction will be
+// called with WebGLTestHarnessModule.TestHarness.reportType.START_PAGE and msg
+// will be the URL of the test. You may return false if you want the test to be
+// skipped.
+//
+// For each test completed the reportFunction will be called with
+// with WebGLTestHarnessModule.TestHarness.reportType.TEST_RESULT,
+// success = true on success, false on failure, undefined on timeout
+// and msg is any message the test choose to pass on.
+//
+// When all the tests on the page have finished your page must call
+// notifyFinishedToHarness.  If notifyFinishedToHarness is not called
+// the harness will assume the test timed out.
+//
+// When all the tests on a page have finished OR the page as timed out the
+// reportFunction will be called with
+// WebGLTestHarnessModule.TestHarness.reportType.FINISH_PAGE
+// where success = true if the page has completed or undefined if the page timed
+// out.
+//
+// Finally, when all the tests have completed the reportFunction will be called
+// with WebGLTestHarnessModule.TestHarness.reportType.FINISHED_ALL_TESTS.
+//
+// Harness Options
+//
+// These are passed in to the TestHarness as a JavaScript object
+//
+// version: (required!)
+//
+//     Specifies a version used to filter tests. Tests marked as requiring
+//     a version greater than this version will not be included.
+//
+//     example: new TestHarness(...., {version: "3.1.2"});
+//
+// minVersion:
+//
+//     Specifies the minimum version a test must require to be included.
+//     This basically flips the filter so that only tests marked with
+//     --min-version will be included if they are at this minVersion or
+//     greater.
+//
+//     example: new TestHarness(...., {minVersion: "2.3.1"});
+//
+// maxVersion:
+//
+//     Specifies the maximum version a test must require to be included.
+//     This basically flips the filter so that only tests marked with
+//     --max-version will be included if they are at this maxVersion or
+//     less.
+//
+//     example: new TestHarness(...., {maxVersion: "2.3.1"});
+//
+// fast:
+//
+//     Specifies to skip any tests marked as slow.
+//
+//     example: new TestHarness(..., {fast: true});
+//
+// Test Options:
+//
+// Any test URL or .txt file can be prefixed by the following options
+//
+// min-version:
+//
+//     Sets the minimum version required to include this test. A version is
+//     passed into the harness options. Any test marked as requiring a
+//     min-version greater than the version passed to the harness is skipped.
+//     This allows you to add new tests to a suite of tests for a future
+//     version of the suite without including the test in the current version.
+//     If no -min-version is specified it is inheriited from the .txt file
+//     including it. The default is 1.0.0
+//
+//     example:  --min-version 2.1.3 sometest.html
+//
+// max-version:
+//
+//     Sets the maximum version required to include this test. A version is
+//     passed into the harness options. Any test marked as requiring a
+//     max-version less than the version passed to the harness is skipped.
+//     This allows you to test functionality that has been removed from later
+//     versions of the suite.
+//     If no -max-version is specified it is inherited from the .txt file
+//     including it.
+//
+//     example:  --max-version 1.9.9 sometest.html
+//
+// slow:
+//
+//     Marks a test as slow. Slow tests can be skipped by passing fastOnly: true
+//     to the TestHarness. Of course you need to pass all tests but sometimes
+//     you'd like to test quickly and run only the fast subset of tests.
+//
+//     example:  --slow some-test-that-takes-2-mins.html
