Playing with lines, some trivial/*-unfilled-* demos works, tri-unfilled-smooth
renders wrong (as one big smooth tri, not as small smooth tre inside unfilled
one). Also, clipping is wrong, as show by tri-unfilled-clip.
This is more playground, hwen i'll have 6 or 8 optimized polygon rendering
functions, it will be much less fun to code all those fixups in driver, so,
t_dd_tritmp.h calling .....
