    PR: 142961
    When bridge apps were in carousel mode, the backing store was inactive
    as its memory had been released. When we rotated the device, we would
    call WebPagPrivate:setViewportSize and resume screen and backing store
    to render and blit visible contents. As backing store was inactive and
    the window usage was GLES2Usage, we were neither doing backing store
    rendering nor direct rendering. Therefore, we drew layers directly
    based on the invalid texture contents when blitting contents if
    accelerated compositing was enabled.
    This patch forces compositing mode to let the accelerated compositing
    layer take care of the rendering which can update texture contents
    before drawing when backing store is inactive and is openGL compositing.
