The camera follow demo does not stop following on compass ornament or double tap zoom

[sargunv]

Since #76 the camera follow demo stops following when any gesture happens, but the double tap zoom gesture doesn't trigger this. Neither does the compass. It seems both are considered "programmatic" rather than gestures? Would be useful to differentiate between built in programmatic and public API programmatic.

Affects both Android and iOS.

material compass part fixed in #179

double tap and SDK compass is still outstanding

I noticed that when the camera follow animation is run, the move reason is programmatic, but when it's not, the move reason is a gesture. It may be because of the execution of cameraState.animateTo() every few hundred milliseconds, which overrides the double tap gesture (see: maplibre/maplibre-native#2790). I limited cameraState.animateTo() executions to 1 per second and the move reason was correctly detected as a gesture.

I'm not sure if it's important, but I also noticed that when the camera follow animation is run and I tap on the map without moving it, it detects it as a programmatic camera movement (double tap, detects 2 programmatic camera movements), but when I tap on the map when there is no animation, it doesn't detect any camera movement.

As for differentiation between the developer's and API's programmatic reasons for camera movement, it seems to be a bug in Maplibre, and it was an issue before the fork on Mapbox (see: mapbox/mapbox-gl-native#10674 (comment))

As a workaround for the demo, we can stop the animation on zoom changes, but it's not a real solution, so probably not a good option.

Yup. We're limited by what the SDK provide here. Calling animateTo so frequently doesn't even work properly on JS.

I'm hoping to solve this by moving the gestures implementation fully into this library. We'll need to reimplement gestures anyway for desktop native, so if we make that common code I hope we can solve this and also get better integration with Compose gesture interop APIs.
