bugref:8153: vboxvideo: ABI issues / software rendering on Linux guest: try using the built-in Solaris OpenGL selection mechanism to put our OpenGL pass-through library in place. We rely on Mesa support being installed. At system start time, when asked to identify ourselves, we check whether pass-through is currently enabled, and if so claim support for the console type as reported by the constype command. To install ourselves, we first run Mesa selection then replace the user library component. On Additions removal we simply re-run Solaris OpenGL automatic selection to restore the system state.
