Daniel Barlow	8ee10214c8	async tile fetcher ... we use cqueues, which is the async framework that lua-http is built on. we integrate it into the glib event loop rather hackily by calling the cqueues event stepper ever 20ms from a glib timeout function overpass has very low rate limits so we handle a 429 response by sleeping for a random length of time and retrying. This is, also, a bit of a hack	2025-06-01 20:50:26 +01:00
