/* Comment from glut.h of classic GLUT:
Win32 has an annoying issue where there are multiple C run-time
libraries (CRTs). If the executable is linked with a different CRT
from the GLUT DLL, the GLUT DLL will not share the same CRT static
data seen by the executable. In particular, atexit callbacks registered
in the executable will not be called if GLUT calls its (different)
exit routine). GLUT is typically built with the
"/MD" option (the CRT with multithreading DLL support), but the Visual
C++ linker default is "/ML" (the single threaded CRT).
One workaround to this issue is requiring users to always link with
the same CRT as GLUT is compiled with. That requires users supply a
non-standard option. GLUT 3.7 has its own built-in workaround where
the executable's "exit" function pointer is covertly passed to GLUT.
GLUT then calls the executable's exit function pointer to ensure that
any "atexit" calls registered by the application are called if GLUT
needs to exit.
Note that the __glut*WithExit routines should NEVER be called directly.
To avoid the atexit workaround, #define GLUT_DISABLE_ATEXIT_HACK. */
