[Mesa-dev] [PATCH] add test for wayland drm, XRGB/YUYV is supported

[Zhao, Halley]

You are right Eric, it just draws some visual blocks on overlay plane.
Now, I sent the patch to wayland/Weston.
Since YUY2 buffer renders to overlay; I don't have a way to read it back. So conformance test is not available.

In this case, EGL is used but hidden by weston and wayland-drm; 
wl_drm_create_buffer() will invoke Weston function, and finally goes to dri2_wl_reference_buffer in $mesa/egl/drivers/dri2/egl_dri2.c.

I can't create a case in X11 environments, because:
1. in X11, XV use XvShm instead of depends on EGL.
2. app/client can't render to overlay plane directly, because overlay related ioctls are defined with DRM_MASTER (no DRM_AUTH). So in X11, only xv driver can render to overlay.
