reduce gps points

[Schuyler Erle]

I don't know of any PHP implementations offhand, but search the Net
for "Douglas-Peucker" line simplification, which we've used
successfully for that purpose. I found a C++ implementation on the web
which I success fully  cargo-culted to Python (and hope to port to
ogr2ogr one of these days).
