[ka-Map-users] dynamic route display

[David Bitner]

I know that there are some folks on the mapbuilder list who have been
working on implementing a three tier approach to displaying lines and
polygons.

If VML is implemented, it uses it.
If SVG is implemented, it uses it.
Otherwise it uses Walter Zorns library.

I think it would be good if a generic library for drawing vectors
could be developed that could be used across these different
applications rather than something built specifically for KaMap.
