------- Additional Comments from Joe Thomas <joethomas at motorola.com>
Added Abstract interface class for fetching the Viewport size.

I ran Parser/html5-full-render on Mac Snow-Leopard with webkit revision r110376
with and without the new patch and below are the values

Webkit rev 110376 - {16540.5ms, 16448ms, 16431ms, 16506.5ms, 16580ms}

Webkit rev 110376 with Patch - {16463ms, 16517.5ms, 16593ms, 16543ms, 16506ms}


The values looks more or less same in Mac SL but there is a variation of around
150-200 ms. Is it possible test the patch on performance bots for any possible
regressions?
