About options

[Jocelyn Fréchot]

While trying to figure out what should be added to the documentation,
I cannot see any difference between the GLUT_ACTION_CONTINUE_EXECUTION
and GLUT_ACTION_GLUTMAINLOOP_RETURNS values of the
GLUT_ACTION_ON_WINDOW_CLOSE option.  Both lead to a call to
fgDeinitialize() and the exit of the main loop.  The only thing I can
see is in the Win32 fgWindowProc function: PostQuitMessage() may be
called or not.  But I guess this not makes a big difference.

Does this mean GLUT_ACTION_CONTINUE_EXECUTION is now deprecated, since
it does not make freeglut stay in the main loop, or am I missing
something?

Other topic: what is the purpose of the GLUT_INIT_* options?  They are
redundant with the glutInit* functions, except that you cannot call
glutSetOption() before calling glutInit().

To answer the "GLUT_ACTION" question, the question at hand is what happens when the user closes a window by clicking on the "X" in the upper right hand corner.  "Continue execution" is supposed to stay in the main loop; "main loop returns" is supposed to return control to the calling program.  The default behavior--which is what GLUT does--is to stop executing the program immediately.

False alarm: the “continue execution” action makes sense (and works as
expected) when there is more than one window.
