Found free font meslo, a version of menlo online at github:

https://github.com/andreberg/Meslo-Font

downloaded Meslo LG v1.0.zip

downloaded and compiled otf2bdf
http://sofia.nmsu.edu/~mleisher/Software/otf2bdf/

Converted MesloLGM-Bold.ttf to our internal menlo font using otf2bdf
default size 12 was perfect.

Converted MesloLGM-Bold.bdf to mgMenlo12.c
with Hiram's utility bdfToGem.

Added the new font to src/lib/font/
Added the declaration to src/inc/memgfx.h

Added checkbox to phyloPng to allow optional
use of the monospace font.
