Testcases: init pointer in a predictable position

Tests may disturb the pointer in their normal operation that may lead to
unexpected results in later tests using that display. Reset the pointer
before a test begins to (0, 0) to save test developers from related
"gotchas" and reduce multi-monitor test boilerplate.
