Datapixx(‘EnableVideoClutTransparencyColorMode’);

M16 video mode supports an overlay whose colors are loaded via SetVideoClut.
This function allows one CLUT color to indicate transparency, permitting the
underlying M16 pixel to show through.
This feature could be used in dual-display environments where overlay
information might be shown on the console,
whereas the main testing display would show only the underlying stimulus.
See DatapixxM16Demo for an example.
