imgui_impl_glut.h

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

// !!! GLUT/FreeGLUT IS OBSOLETE SOFTWARE. Using GLUT is not recommended unless you really miss the 90's. !!!
// !!! If someone or something is teaching you GLUT in 2020, you are being abused. Please show some resistance. !!!
// !!! Nowadays, prefer using GLFW or SDL instead!

// Issues:
//  [ ] Platform: GLUT is unable to distinguish e.g. Backspace from CTRL+H or TAB from CTRL+I
//  [ ] Platform: Missing mouse cursor shape/visibility support.
//  [ ] Platform: Missing clipboard support (not supported by Glut).
//  [ ] Platform: Missing gamepad support.

// 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.
