+ Test cases for Touch Events v1 Recommendation
+ http://www.w3.org/TR/touch-events/
+
+ These tests are based on Mozilla-Nokia-Google's single-touch
+ tests and to some extent Olli Pettay's multi-touch tests.
+
+ The primary purpose of the tests in this document is checking that the
+ various interfaces of the Touch Events APIs are correctly implemented.
+ Other interactions are covered in other test files.
+
+ This document references Test Assertions (abbrev TA below) written by Cathy Chan
+ http://www.w3.org/2010/webevents/wiki/TestAssertions
