b82170336f tiffenc: initialize return value 
'ret' can only be used without initialization if s->height <= 0, which can
only happen if avctx->height <= 0, which is validated elsewhere. Doesn't hurt
to still initialize it though.

bae05e5326 matroskaenc: write correct Display{Width, Height} in stereo encoding 
should be the raw amount of pixels (for example 3840x1080 for full HD side by
side) and the DisplayWidth/Height in pixels should be the amount of pixels for
one plane (1920x1080 for that full HD stream)."

So, move the aspect ratio check in the mkv_write_stereo_mode() function
and always write the embl when stereo format and/or aspect ration is set.
Also add a few comments to that function.
