How to create a repeating sprite?

If I want a box with a repeating sprite using Unity3d, in 2d mode, is that possible? And if so how do I do it? I want to create a background by repeating a small image.

Sprites don’t support tiling or offset properties.

This is quite easy to do with a simple script and nothing else except a sprite renderer. See my answer at the link below for more details (note it might not be live yet since I’m awaiting moderator approval).
