Setting the animation speed of GIFs

Is there a way to set the animation speed (or the delay between each frame which is basically the same) for animated GIFs?

The issue names no files, tests, or entry points. Start by locating Glide's animated-GIF decoding and playback code, then determine whether frame delay is configurable; done would require a clearly defined supported behavior and verification of the resulting animation speed.
