      xwayland: Add glamor egl_backend for EGLStreams · 54ac0971
      Lyude Paul authored
      This adds initial support for displaying Xwayland applications through
      the use of EGLStreams and nvidia's custom wayland protocol by adding
      another egl_backend driver. This also adds some additional egl_backend
      hooks that are required to make things work properly.
      
      EGLStreams work a lot differently then the traditional way of handling
      buffers with wayland. Unfortunately, there are also a LOT of various
      pitfalls baked into it's design that need to be explained.
      
      This has a very large and unfortunate implication: direct rendering is,
      for the time being at least, impossible to do through EGLStreams. The
      main reason being that the EGLStream spec mandates that we lose the
      entire color buffer contents with each eglSwapBuffers(), which goes
      against X's requirement of not losing data with pixmaps.  no way to use
      an allocated EGLSurface as the storage for glamor rendering like we do
      with GBM, we have to rely on blitting each pixmap to it's respective
      EGLSurface produ...
