L. David Baron 2de5593d67 Bug 989802 - Round viewport units to appunits using trunc rather than round so that repeated uses fit within a container. r=roc
viewport-units-rounding-1.html fails without the patch and passes with
the patch.

viewport-units-rounding-2.html fails with an early version of the patch
but not without the patch or with the final version.

Really, though, anything that is a multiple of 5vw will always
produce a round number of appunits when starting from an integer
number of pixels, since 5vw is 1/20 of the viewport.
So, more interesting:
