// ImGui Platform Binding for: FreeGLUT
// This needs to be used along with a Renderer (e.g. OpenGL2)

// Issues:
//  [ ] Platform: GLUT is unable to distinguish e.g. Backspace from CTRL+H or TAB from CTRL+I

// You can copy and use unmodified imgui_impl_* files in your project. See main.cpp for an example of using this.
// If you are new to dear imgui, read examples/README.txt and read the documentation at the top of imgui.cpp.
