Options that I want to implement but don't know how

Dropped Options

Problems

function bool SafePoly4i( int Direction , int p0 , int p1 , int p2 , int p3 , 
        optional name ItemName, optional int PolyFlags )
{
    if( isCoplanar4v(getVertex(p0),getVertex(p1),getVertex(p2),getVertex(p3)) )
        LogPoly4i( Direction , p0 , p1 , p2 , p3 , ItemName, PolyFlags );
    else
    {
        LogPoly3i( Direction , p0 , p1 , p2 , ItemName, PolyFlags );
        LogPoly3i( Direction , p2 , p3 , p0 , ItemName, PolyFlags );
    }
}

Tarquin: the above function has the right order for 4 vertices whether in one square or two triangles. The safety-checking isn't quite up to scratch, so you can try it as is, but it will probably end up making triangles in cases when it shouldn't. BTW, I've put a link to this page on [User Projects]? instead of RC. I don't think there's that many people who are making brushbuilders, so it's not really top news.
