Take another sweep for known globals

[Conduitry]

(Opening in favor of sveltejs/rollup-plugin-svelte#73)

Our list of known globals is still somehow missing Event. We should probably take another sweep (through MDN? somewhere else?) for a list of the the most famous ones and add them to the set here.

Here is Event, and some other interfaces based on it, listed.

And just for reference, here are all globals on MDN listed.

How to decide what to add to the list, I don't know. But please let me know if I can help in any way.

Folks at TypeScript generate comprehensive files:

https://github.com/microsoft/TypeScript/blob/master/lib/lib.dom.d.ts
that file has 863 declare statements, 135 of which are event handlers. This is a lot more than current Svelte globals and doesn't include builtins like Array 😅

https://github.com/microsoft/TypeScript/blob/master/lib/lib.es5.d.ts that one contains basic globals, around 40 of them.

Anyway https://github.com/microsoft/TypeScript/tree/master/lib directory contains various language editions and README with info related to how they collect those declarations.

This is very interesting, I had no idea global namespace is so large

That is a heckin' lot of declarations! 😅

The difference though seems to be that the TypeScript crew needs to have declarations for all ECMAScript objects and functions and whatnot to be able to provide proper typing when using those things in your TypeScript code. In Svelte, we only need to declare the names of globals so that Svelte knows what objects and functions are actually declared when compiling the code.

But maybe it would make sense for Svelte to also check functions and other declarations nested on global objects as well. 🤔I feel like that's an entirely different discussion though. 🤷‍♂️

And please correct me if I'm wrong here.

Object.getOwnPropertyNames(window).

Gives 917 in latest Chrome. The last ~25 are injected by Dev Tools.

I'm getting warnings doing normal event handler things referring to HTMLInputElement and friends, because they're not in the list.

#7786 registered all global objects / functions.
