PointerPinButton

@Composable
fun PointerPinButton(    cameraState: CameraState,     targetPosition: Position,     modifier: Modifier = Modifier,     onClick: () -> Unit = {},     enabled: Boolean = true,     colors: ButtonColors = ButtonDefaults.elevatedButtonColors(),     elevation: ButtonElevation? = ButtonDefaults.elevatedButtonElevation(),     border: BorderStroke? = null,     contentPadding: PaddingValues = PaddingValues(12.dp),     interactionSource: MutableInteractionSource? = null,     content: @Composable BoxScope.() -> Unit)(source)

An elevated button in the shape of a pointer pin on the edge of an ellipsis drawn inside the parent layout, pointing towards some targetPosition off-screen. Only shown if the targetPosition is outside of the ellipsis.

Note that this composable should fill the whole area in which the pointer pin button will be placed, i.e. usually the whole map screen.
