gthumb doesn't rerender avif images on window resize
Mentioned in issue #31. Gthumb pre-renders AVIF images scaled to the current window size, and upscales it to fit inside a larger resized window. This can be fixed by either launching Gthumb at the desired resolution, or by opening a new directory and reopening the one that contains the AVIF image. (With the window at the desired resolution)
