[Xcb] [EXTERNAL] - Attempt at writing a tutorial

[Lucas Augusto Valentim Dantas]

I found those values by looking into the source code, probably libxcb's, since they are passed to the second argument of the function xcb_send_request(), as can be seen here (although the "sequence" argument is gone already): https://xcb.freedesktop.org/ProtocolExtensionApi/#index3h2 but that page doesn't explain what they do.
My goal with this tutorial is to provide enough for the reader to understand the X documentation so he is able to "navigate" on his own, that is what I am trying to do myself.

Those values are for internal use by libxcb (and/or xlib), and are not intended to be used by a normal user of libxcb.

Who is your tutorial intended for? Showing the inner workings is more of a "deep documentation" thing than a "tutorial" thing.

libxcb is a thin wrapper around the X11 protocol. As such, the documentation for those fields can be found at:

https://www.x.org/releases/X11R7.7/doc/xproto/x11protocol.html#request_format

https://www.x.org/releases/X11R7.7/doc/xproto/x11protocol.html#requests:UnmapWindow
