Perhaps we are talking about two different things. But I use canvas (Image - Canvas size) all the time, to make a "canvas" large enough to hold diversely shaped and sized layers from different sources. I also use canvas to crop (rather than scale) an image to a specific size, as it allows me to decide where to position the cropped area.

Kind regards, Elle

In an image, you have multiple layers. Or layers that are larger than the canvas, or smaller, ...

I don't really get the purpose of your question, could you describe your definition of layer and canvas?

The canvas is a sort of layer that contains other layers, such that the inner layers are clipped to the edges of the canvas.

Maybe it would make some sense for the canvas to be a layer group instead, and to have a "clip to group container" checkbox on a layer group. But the canvas is a strong metaphor.

Not to mention that canvas size is a straight reference to the boundaries of physical media (for example an A4 sheet of paper) and it also dictates the size of the exported image (every composition will be cropped to the canvas size when exported to single layer formats) Personally I don't see any reason to revisit these concepts. They describe different things and they are equally necessary.

Even if, unlike Mypaint and Krita, GIMP doesn't have the notion of background patterns? :)
