An Overlay Window that allows input to passthrough

Egui Overlay

In this context, Overlay simply means a gui application where

1. It has a transparent window surface
2. It can toggle the borders/decorations like title bar.
3. can let the input like mouse clicks to passthrough its window surface.

Here, we will let input passthrough when egui doesn't need input.

The project itself builds upon the egui_backend crate while using egui_window_glfw_passthrough for windowing functionality. For rendering, we use egui_render_three_d, as three-d will allow you to draw a bunch of things easily.

For advanced usecases, i recommend directly using egui_window_glfw_passthrough from https://github.com/coderedart/etk

Look at the hello example for a rough idea of how to use this crate.
