/* This is the helper function to run transition tests:
Test page requirements:
- The body must contain an empty div with id "result"
- Call this function directly from the <script> inside the test page
Function parameters:
expected [required]: an array of arrays defining a set of CSS properties that must have given values at specific times (see below)
callback [optional]: a function to be executed just before the test starts (none by default)
Each sub-array must contain these items in this order:
- the time in seconds at which to snapshot the CSS property
- the id of the element on which to get the CSS property value
- the name of the CSS property to get [1]
- the expected value for the CSS property
- the tolerance to use when comparing the effective CSS property value with its expected value
[1] If the CSS property name is "-webkit-transform", expected value must be an array of 1 or more numbers corresponding to the matrix elements,
or a string which will be compared directly (useful if the expected value is "none")
If the CSS property name is "-webkit-transform.N", expected value must be a number corresponding to the Nth element of the matrix
