Servo on Desktop: maybe use libsimpleservo + libui?

I'm not sure about that just yet, but maybe it's worth considering.

I recently added OpenGL support for Mac and Linux, and Windows support via EGL+Angle should not be too hard to achieve. Additionally, the C API appears to work.

The current Desktop servo app is build in Rust. One of the issue with Winit/Glutin is that it requires a full window GL buffer (or some hacky workaround to add widgets). In #21333 I describe a way to build the UI with WR, but maybe a better approach is to build the UI with whatever crossplatform toolkit + language and use Servo via libsimpleservo.

I was thinking of using libui. I am also thinking of not using any of its Rust ports, but directly the C version. Not using Rust at the embedder level is harder, but it's what the rest of the world will be doing anyway.

I've built a proof of concept (requires few tweaks in libui and in servo, but all are WIP PRs) that just render a page (no interactions).

If we go this way, adding url bars, tabs, etc, will be a lot easier.

Nah.

We should have a UIKit view, a UWP control, and a GTK widget. It's really not hard to build.
