DlangUI print too small on retina screens

[Joel via Digitalmars-d-learn]

I got a new computer (another MacBook Pro, but this one has 
retina display), now I don't think I can use my main programs 
(done in DlangUI), without eye strain and having my head close to 
the screen.

I noticed a lot of forked versions of the said library. Do any 
have a fix for the tiny print, if so, which one is good?

Thanks in advance.
