c3 resize image vs c2

C2 resizes pictures better than C3. Keeping the right colors and borders of the picture.

Also, the C2 image editor is much faster. And it's sad for those who use C3 (dark theme)

Have you tried using the Smooth checkbox in the resize dialog?

Keeping it disabled is better for pixel art with clearly defined edges. Enabling it is better for images with smooth color transitions.
