Need help to optimize smartkeyslib text output

[tschak909]

#ColecoAdam #Z88DK Need some help on the SmartKeys proportional font output routines that are in smartkeyslib.
https://github.com/tschak909/smartkeyslib

Currently, the code in smartkeys_putc() https://github.com/tschak909/smartkeyslib/blob/main/src/smartkeys_putc.c will literally plot a single dot for each bit shifted in a row. This is wildly inefficient. 

There is code in SmartWriter for the font output, that is much faster, and could possibly be adapted. https://adamarchive.org/archive/Adam/Technical/ADAM SmartWriter ROM ASM.zip (see the SK_ symbols)

Can anyone help to pitch in? Could really use the help, as I am stretched thin, trying to get FujiNet for Adam to 1.0.
