set viewWidth in RTTBufferManager sets height instead of width

[genesys-zz]

the function set viewWidth has a bug in the branch when _textureWidth is not larger than _viewWidth. it then sets the height of the _renderToTextureRect instead of the width:

    public function set viewWidth(value : int) : void
    {
        if (value == _viewWidth) return;
        _viewWidth = value;

        _buffersInvalid = true;

        _textureWidth = TextureUtils.getBestPowerOf2(_viewWidth);

        if (_textureWidth > _viewWidth) {
            _renderToTextureRect.x = uint((_textureWidth-_viewWidth)*.5);
            _renderToTextureRect.width = _viewWidth;
        }
        else {
            _renderToTextureRect.x = 0;
            _renderToTextureRect.height = _textureHeight;
        }
        dispatchEvent(new Event(Event.RESIZE));
    }

_renderToTextureRect.height = _textureHeight;

must be replaced with

_renderToTextureRect.width = _textureWidth;
