Example: Multiple Windows

[bryphe]

The Revery API supports creating multiple Windows via multiple calls to App.createWindow:

revery/src/Core/App.re

Line 39 in 78811ec

let createWindow =

I'd like to have an example that exercises this behavior. The example could consist of a single Button labeled "New Window". When clicked, App.createWindow would be called with a new Window with a very simple primitive (like, just a <Text /> saying "This is Window X")

There is one blocker to this:

• We need to set up our Windows to share the same OpenGL context. When creating OpenGL assets like buffers/textures/compiled shaders/etc, these are associated with an OpenGL context. The GLFW API supports sharing an OpenGL context between Windows: https://www.glfw.org/docs/latest/context_guide.html (See "Context Object Sharing"). However, our glfwCreateWindow wrapper doesn't support this - we'd need to also add an API for this
• Once we have the glfwCreateWindow API with an additional argument for passing a window context, we can pass/share the context w/ the App.createWindow. The consumer of the API should never have to care about 'Window Context Sharing' - we should take care of that automatically.

Is it possible to have multiple windows at this stage? I can call createWindow multiple times (and I get a window for each call) but the UI is only shown & responsive in the window that I pass to UI.start.

Here is a work in progress for multiple windows support #235
