If a value such as `lat` is not known because there is no fix, it'll be `NaN`.
`hdop` is a value from the GPS receiver that gives a rough idea of accuracy
of lat/lon based on the geometry of the satellites in range. Multiply by 5 to
get a value in meters. This is just a ballpark estimation and should
not be considered remotely accurate.
To get this event you must turn the GPS on
with `Bangle.setGPSPower(1)`.

If Bangle.strokes is defined and populated with data from `Unistroke.new`, the `event` argument will also
contain a `stroke` field containing the most closely matching stroke name.

```
Bangle.strokes = {
up : Unistroke.new(new Uint8Array([57, 151, ... 158, 137])),
alpha : Unistroke.new(new Uint8Array([161, 55, ... 159, 161])),
};
Bangle.on('stroke',o=>{
print(o.stroke);
g.clear(1).drawPoly(o.xy);
});
// Might print something like
{
"xy": new Uint8Array([149, 50, ... 107, 136]),
"stroke": "alpha"
