Subject: [PATCH xserver 23/27] xwayland: Add preferred GLVND vendor to
xwl_screen
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
If Xwayland's EGLstream backend supports hardware acceleration with the
NVIDIA closed-source driver, the GLX library also needs to be one
shipped by NVIDIA, that's what GLVND is for.
Add a new member to the xwl_screen that the backend can optionally set
to the preferred GLVND vendor to use.
If not set, "mesa" is assumed.
