This is a bit sketchy in terms of implementation, with some rough
edges, but for the most part IT WORKS.
That is to say, I get an obvious 3D output when using the
"testdisplay" program from intel-gpu-tools with the "-3" parameter
and outputting to a 3D-capable HDMI display.
Rough edges include: the criteria for when to enable 3D mode
selection, and the inconsistent support for setting InfoFrames on
HDMI outputs.
