The main file would be lib/arrows.c. Each arrow type has a draw_<type>
function, which is called from arrow_draw. You'll also want to change the
arrow selection widgets DIAARROWSELECTOR in lib/widgets.c to include it,
and the DiaArrowPreview stuff in app/lineprops_area.c (which I am not
familiar with).
