Bug 1224251 patch 1 - Add reftests. r=mattwoodrow 

Locally, these tests fail reliably for me without the patch.  I'm not,
however, confident that they would continue to do so, across future
mutations in the code, were the bug to be reintroduced, given the amount
of fiddling I had to go through to get them to fail without the patch.

That is, without the patch:

  table-row-opacity-dynamic-1.html shows the area of the row that's not
  behind the text as a much more opaque blue than it should be (while
  the area of the row that is behind the text is correct)

  table-row-opacity-dynamic-2.html shows the area of the row that's not
  behind the text as the white background showing through (while the
  area of the row that is behind the text is correct)
