Why no fill triangle, fill polygon?

Why no fillTriangle(), fillPolygon() functions implemented?

Found draw_triangle and commented out // {"triangle", draw_triangle_lua} in luaL_reg Module_methods[] at
https://github.com/AGulev/drawpixels/blob/master/drawpixels/src/drawpixels.cpp
Why was it commented?
