// Microsoft's version of gl.h invokes macros that are defined in
// windows.h.  To avoid a conditional #include <windows.h> in
// every file, we wrap gl.h with the proper conditions here, and
// have our source files #include "glwrap.h" instead.

// As a bonus we ensure that all declarations for GLU are included,
// and on X11-based systems, we cover X11 and GLX as well.  This
// should cover nearly everything needed by a typical glean test.

// It's unfortunate that both Windows and Xlib are so casual about
// polluting the global namespace.  The problem isn't easily resolved,
// even with the use of C++ namespace directives, because (a) macros
// in the include files refer to unqualified global variables, and (b)
// preprocessor macros themselves aren't affected by namespaces.

// Windows has a convention for typedef'ing pointers to OpenGL functions

// Identical conventions are being established for Linux, but they are
// not yet in place, and are not necessarily supported in other UNIX
// variants.  Therefore we need a similar mechanism that accomplishes
// the same goal.  We'll use the standard typedef names, but put them
// in the GLEAN namespace; that should preserve as much source-code
