[css-paint-api] Try and find a way to access images w/o using a custom property

[bfgeek]

It might be desirable to have images loaded implicitly in a paint function, without having them loaded via. a custom property.

For example performing a network request, or a pull from the main execution context, to receive an image to use.

Thought: Are there any existing properties today which do this?

The only thing that's kinda close to this is that, theoretically, things like list-style: bullet can render the bullet with an image. There's nothing else in CSS that creates something image-like without the user explicitly asking for a URL.

Aren't bullets & co just unicode glyphs?
(in which case you can draw them using drawText)

For us these are just paths painted onto the canvas.

I can't think of anything which magically accesses a resource on the network magically.

[tabatkins]

Yeah, my point is that they're allowed to be that. In actual browsers they're either text or manually-drawn stuff, but there's nothing preventing them from being a network-fetched url. (It would just be a terrible idea.)

That's the only place where it's even possible, tho. Nowhere else does a built-in CSS property even have a chance of fetching anything.
