[Impeller]When I use Impeller on iOS and use Image.net to load a very long image (image height is more than 25 times the width), the image will be compressed, using skia is no problem. #142794

   With below code sample, below are the results with and without Impeller:

   runnable code sample

   
   import 'package:flutter/material.dart';
   
   void main() => runApp(const App());
   
   class App extends StatelessWidget {
     const App({Key? key}) : super(key: key);
   
     @override
     Widget build(BuildContext context) {
       return const MaterialApp(
         home: HomePage(),
       );
     }
   }
   
   class HomePage extends StatelessWidget {
     const HomePage({Key? key}) : super(key: key);
   
     @override
     Widget build(BuildContext context) {
       return Scaffold(
         body: Center(
           child: Image.network('https://image.dzplus.dzng.com/2024/01/22/1705894299v23semx0woimage.jpeg', fit:BoxFit.cover)
         ),
       );
     }
   }
   
   

   1. With Impeller:

   

   2. Without Impeller:

   

   Is this correct interpretation of the issue you are reporting ?
