If we see this URL; http://www.w3.org/TR/css3-transforms/#backface-visibility-property, the initial value of backface-visibility-property is visible. However TextureMapperLayer use hidden(false) as initial value. This patch is for changing the initial value, hidden to visible.

GraphicsLayer's m_backfaceVisibility is true. We need to sync TextureMapperLayer's value with GraphicsLayer.
