Two fixes based on feedback after the last commit:
1. The map wasn't following the position at all -- only the first fix
recentered, later updates just moved the marker. Now every fix
recenters (easeTo, not flyTo, after the first one, so it doesn't
repeat that zoom swoop on every update) -- matches how
GeolocateControl's own trackUserLocation always behaved.
2. GNSS should only be used when explicitly turned on via the sidebar
"GNSS" icon, not whenever a receiver happens to have a fix --
simpler to test against the simulator that way, and puts the
visitor in control of whether GNSS is engaged at all. GnssControl
now owns following the map on its own (same flyTo-once/easeTo-after
pattern) whenever it's enabled; LocateControl checks
GnssControl#isEnabled() and, when true, just jumps to
#getPosition()'s current fix and reuses its existing .gnss-marker
instead of polling/marking on its own. Only falls back to the
browser's own geolocation when GNSS is off.
Verified end to end with the GNSS simulator: enabling sidebar GNSS
recenters immediately and keeps following over several polls;
clicking Locate while GNSS is on jumps to the same position without
creating a second marker or touching its own active state; turning
GNSS back off and clicking Locate correctly falls through to the
browser geolocation path instead.
Restructure the map controls from MapLibre corner buttons into a left
sidebar of icons with flyouts/panels (radar, GPX, GNSS), matching
OsmAnd's layout more closely:
- Base map and GPX selection are now full-height side panels docked
next to the sidebar (not small dropdown flyouts or a right-docked
panel), opening/closing exclusively via a small shared event bus
(panels.js) so only one is ever open at a time.
- The GPX panel's upload/new-folder controls are now icon buttons in
the header instead of an always-visible dropzone and form; dragging
a GPX file onto the tree, a specific folder, or straight onto the
map itself all upload it.
- New: Maptool::GpsdClient (lib/maptool/gpsd_client.rb) streams live
GNSS fixes from a local gpsd daemon over Server-Sent Events
(/api/gnss/stream) to a marker on the map (public/js/gnss.js) — one
background gpsd connection shared by every browser tab.
- The online map style (public/js/osmand-style.js) is now styled to
resemble OsmAnd's own rendering, applied to both the online and
offline (PMTiles) styles.
Also adds a GeolocateControl (browser geolocation) next to the zoom
controls.
