Currently, chromium port handles m_contentsVisible like m_drawsContent.

void GraphicsLayerChromium::updateLayerIsDrawable()
{
    // For the rest of the accelerated compositor code, there is no reason to make a
    // distinction between drawsContent and contentsVisible. So, for m_layer, these two
    // flags are combined here. m_contentsLayer shouldn't receive the drawsContent flag
    // so it is only given contentsVisible.

    m_layer.setDrawsContent(m_drawsContent && m_contentsVisible);

    if (!m_contentsLayer.isNull())
        m_contentsLayer.setDrawsContent(m_contentsVisible);

    if (m_drawsContent)
        m_layer.invalidate();

    updateDebugIndicators();
}

Some web developers think visibility:hidden causes to save the texture memory.
