REVISION SUMMARY
  This implements a wrapper class for the wl_eglstream_controller Wayland interface. It allows clients to inform the compositor when a new EGL Stream has been created with an Wayland surface attached as its producer. The compositor can then bind a GL texture as the stream's consumer allowing it access to the surface's buffer contents for presentation. The only client currently expected to make use of this interface is the NVIDIA EGL driver when running alongside a compositor supporting EGLStream-based buffer sharing.

REPOSITORY
  R127 KWayland
