Pixel-snap box size before computing -webkit-box-reflect offsets.

This is particularly important when -webkit-box-reflect interacts with
blur (which clamps at edges, and which we don't want to pick up a row of
incorrectly transparent pixels at the edge).

Prior to the change, the added test shows, in each of the four sets of
four lines, rounding glitches through most of the second half of the
first row of tests and most of the first half of the fourth row of
tests.
