Yeah, it is hard to do properly. Been looking into several different methods and implementations, and this is the one I went with on my project (missing from the article): Shader-Based Antialiased, Dashed, Stroked Polylines http://jcgt.org/published/0002/02/08/ http://jcgt.org/published/0002/02/08/ This is a very throughout implementation with many different drawing features and beautiful results. The actual implementation provided with the Python examples is a bit difficult to understand and not perhaps the most optimal, but still the paper and the theory behind it is one of the most comprehensive I've found.
