multi_window example too simple

[PerBothner]

This isn't really a feature request but rather a request to enhance the example applications.
Warning: I am quite new to Rust, and it is quite likely an experienced Rust programmer would not have these problems.

I'm trying to create multiple non-trivial windows in the same application. The examples/multi_window.rs is a bit too simple, in that window2 is relatively simple and very different from window1. I'd like openWindow to create the same kind of window, which means using the same new_window function/closure to create both. But then I get into nasty move/ownership issues, which I haven't been able to solve, so far.

Attached is what I have so far. It builds and runs - but as soon as I uncomment the second new_window call I get lots of errors. What is the clean/recommended way to get that functionality? (Feel free to use anything in my code that you find useful if you enhance the examples.) The use of "http://example.com" is just a place-holder. Most likely would be to enhance the UserEvent::NewWindow to pass suitable options from JavaScript to the rpc-handler to the event_loop handler.

Note I also used the seemingly-newer EventLoop::with_use_event idiom from custom_titlebar.rs, instead of the mpsc::channel logic from multi_window.rs.

If someone with more Rush experience has a suggestion for a general approach, I can probably work out the details.

I tried converting variables to static items. However, some of them are mutable, and mutable statics aren't thread-safe. Using a bunch of unsafe code didn't seem like a promising approach.

Maybe paste your initial code here or Discord so we can help you.

Thank you! I managed to modify my dt-wry front-end based on your example. Running the command domterm -Bwry multiple times creates multiple windows using a single dt-wry executable. I also added support for a --geometry option.

The source code is here.
