[gipy] Bigger area fails to covert

[pavelmachek]

Smaller area works ok (resulting in 130K file). But when trying to prepare for 1-hour car trip (and slightly bigger area), I press "convert", then get warning about page not responsive, and then nothing.

Would it be possible to upload just the gpx track to watch (without surrounding map), or maybe have low fidelity map with just big towns and major roads for such use?
