MarkerView Plugin

[fynngodau]

The marker view plugin has multiple issues at this moment that make it infeasible to be used in some cases.

• Right now, each and every marker added through it is a View. Sometimes you need many markers and only show details on click, which would right now require, as far as I can tell, removing the "normal", performant marker (rendered with native code) and replacing it with a MarkerView.
• All the markers being views also results in some latency relative to the map moving. So far I haven't been able to figure out how to position views on top of the map exactly in sync with the map. It feels like it should be possible – maybe it is easier to achieve if this feature is moved to maplibre-native and there's some code to support synced rendering there.

Additional info: I have written code for microG's maps that implement Google Maps info windows. Maybe this can be useful somewhere, just wanted to mention it here. MapLibre-native itself also has such an imementation for its own marker annotation implementation.
