Fixes #344
Currently
TileOverlayImplappends raster layers to the top of the Mapbox style stack withstyle.addLayer(), ignoringzIndexcompletely. In apps like Google Photos (the "Explore / Places" photo heatmap view), the tile overlays end up rendering on top of photo markers and pin labels instead of underneath them.Changes:
TileOverlay.kt: usestyle.addLayerBelow()targeting the lowest active annotation layer (fillManager,lineManager, orsymbolManager), falling back tostyle.addLayer()if no annotations exist yet.GoogleMap.kt: addreorderTileOverlays()to sort active overlays byzIndexbeneath annotation layers. Call it when adding overlays, changingzIndex, clearing the tile cache, or when styles reload.tileOverlaysinGoogleMapImpl.clear().Tested on a POCO F1 running Android 15 with Google Photos.
