flashplayer11 b1 071311 api change

[profelis]

Stage3D.viewport has gone.

"General authoring note: This release includes an update to the Stage3D APIs that removes the
Stage3D.viewport property. Developers should instead use the Stage3D.x and Stage3D.y properties.
Width and height can only be set using the Context3D object. Existing content using the Stage3D.viewport API will need to be updated to run with this and future builds of Flash Player and
AIR."

See comments in http://away3d.com/forum/viewthread/581/ for the workaround. I have a patch for the workaround, but I'm not sure where to post it.
