Ebiten backend for cimgui-go

originally created by Gabriel Ochsenhofer as ebiten-cimgui updated by Brett Bronson as cimgui-go-ebiten then it was cloned and modified here by @gucio321 in terms of the LICENSE.

Usage

As ebiten is not (thankfully) a C library, we can make it a separated package :tada:.

You can use it as another backends for cimgui-go.

        backend, _ = imgui.CreateBackend(ebitenbackend.NewEbitenBackend())
