Since off-main thread animation (OMTA) is not available on all platforms we
define a common wrapper function that runs OMTA tests only when available. This
patch further performs an internal check of basic OMTA operation so that
only a single error is produced if OMTA is unexpectedly unavailable.
Typical usage is:
SimpleTest.waitForExplicitFinish();
runOMTATest(function() {
... test code ...
SimpleTest.finish();
},
SimpleTest.finish);
This can be easily wrapped with promises if needed but does not require using
promises.
The calls to waitForExplicitFinish and finish are not performed automatically
since this function may be integrated with test suites that do other work
outside the call to runOMTATest.
