+// 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).

+//

+// fl_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 fl_create_gl_context is provided to create it for any

+// X visual.

+//

+// fl_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...

+//

+// fl_no_gl_context clears that cache so the next fl_set_gl_context is

+// guaranteed to work.

+//

+// fl_delete_gl_context destroys the context.

+//

+// This code is used by Fl_Gl_Window, gl_start(), and gl_visual()
