// This file supports translating W3C tests
// to tests on auto MochiTest system with minimum changes.
// Author: Maksim Lebedev <alessarik@gmail.com>
// Since web platform tests don't check pointerId, we have to use some heuristic
// to test them. and thus pointerIds are send to mochitest_support_external.js
// before we start sending synthesized widget events. Here, we avoid using
// default values used in Gecko to insure everything works as expected.

// Setup environment.
addListeners(document.getElementById("target0"));
addListeners(document.getElementById("target1"));
// Setup communication between mochitest_support_external.js.
// Function allows to initialize prerequisites before testing
// and adds some callbacks to support mochitest system.
