FriCAS specifies the following fonts:
-adobe-courier-medium-r-normal--18-*-*-*-m-*-iso8859-1
-adobe-courier-medium-o-normal--18-*-*-*-m-*-iso8859-1
-adobe-courier-bold-r-normal--18-*-*-*-m-*-iso8859-1
-adobe-courier-bold-o-normal--18-*-*-*-m-*-iso8859-1
Fonts matching that appear in output of xlsfonts on my machine,
which IIUC means that they are available.

AFAIK scalable fonts are supported. You may be thinking about old
news that FreeType dropped support for hints in fonts. This
was after a patent dispute, but FreeType folks claimed that
they get better results without hints.

IIRC we had some discussion about fonts several years ago.
My understanding was that available fonts differ widely between
systems, in particular there are silly renamings due to trandmark
reasons and essentially identical fonts with widely different
names. Anyway, the discussing did not found better default
than the one we have now.
