Redraw tiles once per burst of tiled-marker changes - #18

Conversation
Relabelling street trees changes a few dozen tiled markers at once, and each change went through update() separately: - the raster source was replaced per marker, and the map fetched every visible tile again each time (45 replacements, 494 tile renders, the last tile 6.1 s after the change, on a Pixel 5a); - renderer.onPostProcess() copied all 144k entities to redraw the native ones, although nothing native had changed (50 ms each, 2.3 s in total); - the icon was baked and all entities copied just to count them. Now changes arriving within a frame share one source replacement, onPostProcess runs only when a native marker became tiled, the icon is baked only for a native marker, and the count is read without copying. Same burst: one replacement, 19 tile renders, the last tile 0.25 s after the change.

Per-marker updates on tiled markers swapped the raster layer and ran
onPostProcess(copying ~144k entries) once per marker. Relabelling the street-tree sample took ~6.1 s.onPostProcessunless the marker was native before.Street-tree relabel: 6.1 s → 0.25 s on Pixel 5a.
