This code is new, and unrelated to the fix. If there is nothing to scale, return the original image instead of doing extra work.

Nit: How about making these color string representations (e.g. @"1 0.776471 0 1") consts with descriptive names so they can be reused and seem less like a magic value?

I can do that for the two tests that are the same. These exact values would changes based on how small the image is scaled.

UIGraphicsBeginImageContextWithOptionsisn't technically deprecated, butAPI_TO_BE_DEPRECATED. However, according to reports it's crashing in iOS 17. Replace usage withUIGraphicsImageRenderer, available in iOS 10.I kept introducing horizontal flipping bugs when I was writing this, but it wasn't causing test failures. Changed the test images from a single color to a gradient with different colors in each corner, then updated the tests to confirm the orientation is still correct.
Generated the test image with ImageMagick:
Also avoid doing extra work if there's nothing to scale, and return the original image.
Fixes flutter/flutter#144602
