This test verifies that the CTM fetched by getScreenCTM is a snapshot value of the current animated state.
The CTM values are inspected on 'beginEvent', 'endEvent' and 'repeatEvent' times. The expected values are
calculated from the SMIL Animation equations and the current document time.
The test has passed if the testcase reports "Results match expected values." 8 times, and each such string
is prefixed with a green rectangle. When this happens the text in the rect with blue stroke changes from
'failed' to 'passed'.
