borderline: Simplified BorderLinePrimitive

Overhauled BorderLinePrimitive to use two constructors
offering using one or three edge definitions for
construction to better refrlect possibilities. Adapted
usages. Better processing, less memory. Preparation
for using more decent LineExtend values (four per line
needed)
