    x11-toolkits/wlroots: slightly expand NVIDIA note
    
    Nothing to do in this port until NVIDIA fixes FreeBSD driver:
    - both GBM (495+) and EGLStreams require nvidia-drm.ko
    - wlroots-eglstreams is supported as NVIDIA option (since f406592a8e37)

    Wayland "de facto" requires DRM for mode setting (KMS) and buffer
    sharing (GBM, EGLStreams). Without those one can sacrifice convenience
    and performance by starting under Xorg with software rendering e.g.,
    
      $ startx
      $ glxinfo | fgrep 'OpenGL renderer'
      OpenGL renderer string: NVIDIA GeForce GT 640/PCIe/SSE2
      $ cage glxinfo | fgrep 'OpenGL renderer'
      OpenGL renderer string: llvmpipe (LLVM 13.0.1, 256 bits)
    
      $ sway -d
      [...]
