imgui-rs: Rust bindings for ImGui

Ultra hyper turbo cyber mega extra über experimental!!!

ui.window()
    .name(im_str!("Hello world"))
    .size((300.0, 100.0), ImGuiSetCond_FirstUseEver)
    .build(|| {
        ui.text(im_str!("Hello world!"));
        ui.text(im_str!("This...is...imgui-rs!"));
        ui.separator();
        let mouse_pos = ui.imgui().mouse_pos();
        ui.text(im_str!("Mouse Position: ({:.1},{:.1})", mouse_pos.0, mouse_pos.1));
    })

Currently implemented things

• Low-level API (imgui-sys)
• Renderer for easy integration with Glium projects (optional)
• Parts of high-level API
• Not horrible way of defining and passing null-terminated UTF-8 to ImGui
• Parts of imgui_demo.cpp reimplemented in Rust as an API usage example (examples/test_window_impl.rs)

Important but unimplemented things

• Documentation (rustdoc)
• Support passing a custom Program to Glium renderer (e.g. from a shader cache, or custom shader)

Core design questions and current choices

• Closures VS begin/end pairs (current choice: closures)
• Mutable references VS return values (current choice: mutable references)
• Passing around Ui<'ui> VS passing around &'ui Ui (current choice: Ui<'ui>)
• Splitting the API to smaller pieces VS all draw calls in Ui (current choice: all draw calls in Ui)
• Builder pattern for optional arguments VS something else (current choice: builder)
• Mutation functions in builders VS self-consuming functions in builders (current choice: self-consuming)
