 * The volume given in Sound.play now over-rides that set in Sound.addMarker if specified (fix #623)
 * BitmapDatas when used as Game Object textures in WebGL now update themselves properly.
 * Timer.ms now correctly reports the ms time even if the Timer has been paused (thanks Nambew, fix #624)

 * ArcadePhysics.Body.setSize corrected to take the parameters as positive, not negative values.
 * ArcadePhysics.World.seperate will now check gravity totals to determine separation order. You can set World.forceX to true to always separate on X first and skip this check.
