Import SDL 1.2.14 and GLEW 1.5.4.

I am not replacing the following header files used by the Windows build,
as I don't have a Windows build setup to test. Please point the Windows
build at the header files inside these clean distribution packages and
garbage collect the duplicates: GLew/*.h and SDL/Include_1.2.

+.PP
+\fBSDL_QuitEvent\fR is a member of the \fI\fBSDL_Event\fR\fR union and is used whan an event of type \fBSDL_QUIT\fP is reported\&.
+.PP
+As can be seen, the SDL_QuitEvent structure serves no useful purpose\&. The event itself, on the other hand, is very important\&. If you filter out or ignore a quit event then it is impossible for the user to close the window\&. On the other hand, if you do accept a quit event then the application window will be closed, and screen updates will still report success event though the application will no longer be visible\&.
