**Short description of error**
Stereoscopy renders always appear as anaglyph, until you save them.
**Exact steps for others to reproduce the error**
Open blender with a camera pointing at a camera
Go into scene view and turn on;
- Stereo 3D mode (not Multi-View)
- Views > Stereo 3D (not individual)
Do a test render and notice how the blender render window shows anaglyph fine.
Switch to a different stereo mode eg Top-Bottom and notice how the render still displays an anaglpyh image.
On saving the image, the correct stereo 3d encoding is applied to the image, be it anaglyph or Top-Bottom
The blender render window should show the stereo encoding in all modes, otherwise new uses assume they haven't set it up correctly.
