Typography is hard and takes up a lot of cpu time. Even though AmigaOS had support for proportional fonts with bullet.library, I would still use Topaz, MicroKnight, p0t-n00dle or some other fixed 88 or 816 font for Workbench. The example code for the Amiga with bullet.library seemed OK on the 8MHz cpu (7.xx MHz) and would be fast enough maybe with 1 bit plane, but when the Amiga is advertised as a colour computer people would complain why it's only 1bitplane, although the Amiga DTP program did that and in interlace as well. Early 1980s Atari TOS/GEM had the windows aligned on 16 pixel boundaries (M68k word length) to make redrawing easier and faster, I don't know if early Macontish System 1.X had that as well to speed it up on 8Mhz M68K CPU.
