Downscaled images are very pixelated

[pixartist]

I have a container with several sprites which scales dynamically with the window size. Unfortunately the downscaling produces very pixelated edges for my sprites. 

Here you can see the effect: http://i.imgur.com/AzgiyjA.png

The scaling is done linearly (by default) and can be nearest if you specify it. If that scaling mode doesn't produce the desired effect you will likely want to scale it outside the app.
