* transitions/change-values-during-transition.html:
isEqual: Remove unnecessary code - tolerance always passed in and always default value.
getXPosition: Extract into a function, since it is duplicated twice.
check2: Still run second check if the first fails, just give more debugging output.
start: Remove final setTimeout - nothing changes between the end of check2 and here,
    so this is just making the test take 100ms longer.
