// Internal interface to set up OpenGL.
//
// A "Fl_Gl_Choice" is created from an OpenGL mode and holds information
// necessary to create a window (on X) and to create an OpenGL "context"
// (on both X and Win32).
//
// create_gl_context takes a window (necessary only on Win32) and an
// Fl_Gl_Choice and returns a new OpenGL context. All contexts share
// display lists with each other.
//
// On X another create_gl_context is provided to create it for any
// X visual.
//
// set_gl_context makes the given OpenGL context current and makes
// it draw into the passed window. It tracks the current one context
// to avoid calling the context switching code when the same context
// is used, though it is a mystery to me why the GLX/WGL libraries
// don't do this themselves...
//
// delete_gl_context destroys the context.
//
// This code is used by Fl_Gl_Window, gl_start(), and gl_visual()
