3D/Stereo preview on Hololens Emulator
Hololens let's you render on 2 backbuffers(stereoscopic) but it's hard to know if the output is correct because the emulator shows just one frame. I assume it's the image for either the left or right eye.
When hololens is in stereo mode, show both frames on the emulator. Let the user choose between spit-screen or Anaglyph (Red-Cyan).
