Use special renderer for canvases and paintings which will show their content in inventory and in hand. This will help to identify needed paintings and use Artist Table more easily.

Currently the painted canvases all look the same until you put them into the artist table. I'm working on creating a 2x4 painting which requires that I break down the project into smaller constituent parts and then merge them. Trying to figure out what piece goes where and having to guess which is which is a little bit frustrating so it'd be nice if once they were painted on, it showed what was on them--just a thought. Thanks :)

There are currently disabled methods in CanvasItem#initializeClient and renderer in CanvasItemRenderer which was partly done but removed in 1.18-1.19 migration.
