composite multiple images into one
If this already exists please delete. If not it would be nice to composite multiple images into one image. Good for sprites.
ImageResizer isn’t the appropriate tool for sprite generation – sprite generation should be done offline or during asset compilation instead of on-the-fly. Sprite generation is also an anti-pattern in HTTP2, as it causes extreme client RAM use and worsens mobile performance, and doesn’t offer benefits when pipelining is available.
