I changed this part of the API so there's no mixing the 2d mode
structure with the 3d flags. Now (v4 of the series) userspace receives
one struct drm_mode_modeinfo for the 2D mode (like before) and one
struct drm_mode_modeinfo for each 3D layout (and the rest of the timings
are from the "underlying 2D mode" that userspace can use in conjonction
with the layout bit to compute the stereo framebufer layout)

HTH,
