1) something which can be done, but has not yet been done?

We just haven't bothered: not very many DOS apps use it because it's very
slow to write pixels using the BIOS. But apparently you found one. I could
implement it fairly quickly now; it would require writing a
vgaemu_put_pixel function in src/env/video/vgaemu.c and interfacing to it
from int10.c.
