OK. That will be an 8 sided polygon.

That is fine with me. I will the add new function defines to lynx.h like:

#define tgi_sprite(spr) tgi_ioctl(0, (void *)(spr))
#define tgi_flipscreen() tgi_ioctl(1, 0)
#define tgi_setbgcolor(col) tgi_ioctl(2, col)

This makes things less portable, but they are really required.

Obviously I also need to write some magic code to transfer cputc
output to a tgi_outtext call if I want to have conio to work on
the Lynx.

PS. I know very little about the hardware for other cc65 platforms.
    The Lynx is full of all kind of graphics accelerators as it was
    designed to be a games console. So my views are a bit Lynx-biased.
