I too keep an eye out for things XTerm / Sixel (raster?) / ReGIS 
(vector) related.  I learned about Sixel first, became quite interested, 
and then about ReGIS.

I've since learned about GDM (?term?) graphics on 3279 (?model?) on 
mainframes.  I've not yet managed to reproduce this myself, but I've 
seen pictures.

I hope this goes without needing to be said, but for people reading this 
archive in the future, we're talking about the terminal actually 
supporting and displaying graphics, not some pseudo overlay / alpha 
background that some more mainstream terminal emulators use.

XTerm on macOS?  Please tell me more.  I'm currently using iTerm2 as 
it's considerably better than Terminal from Apple.  Though, it does seem 
as if iTerm2 supports Sixel.  I think I heard some noise about ReGIS 
support in future versions.  (I think it was ReGIS.  Maybe it was that 
Sixel was coming when I last read about it.)

I'm not up on DEC software.  I think that there is a full DEC terminal 
emulator that some versions of may support graphics, though I don't know 
what type.  I think there was also an XTerm profile / nickname that 
included DEC.  (Or am conflating AIXterm?)
