And just what the fuck is that?  Well, it's LPGL3+ and these FOUR simple stipulations.
1. These and all comments are to remain in this document
2. You will not post this software in a repository or a location for others to download from:
   A. Unless you have made 10 lines of changes
   B. A notice is posted with the code that it is not the original code but instead derived from an original
3. Forking is OK and does NOT require any changes as long as it is obvious forked and stated on the page
   where your software is being hosted.  For example, GitHub does a fantastic job of indicating if a repository
   is the result of a fork.
4. The "Official" version of PySimpleGUI and the associated documentation lives on two (and **only** two) places:
       1. GitHub - (http://www.PySimpleGUI.com) currently pointing at:
          https://github.com/PySimpleGUI/PySimpleGUI
       2. PyPI - pip install PySimpleGUI is the customary way of obtaining the latest release
       
       THE official documentation location is:
          Read the Docs (via http://www.PySimpleGUI.org).  Currently is pointed at: 
          https://pysimplegui.readthedocs.io/en/latest/
   If you've obtained this software in any other way, then those listed here, then SUPPORT WILL NOT BE PROVIDED.

-----------------------------------------------------------------------------------------------------------------

How about having FUN with this package??  Terrible note to begin this journey of actually having fun making
GUI based applications so I'll try to make it up to you.

The first bit of good news for you is that literally 100s of pages of documentation await you.  And nearly 200
Demo Programs have been written as a "jump start" mechanism to get your running as quickly as possible.

Some general bits of advice:
Upgrade your software!  pip install --upgrade --no-cache-dir PySimpleGUI
If you're thinking of filing an Issue or posting a problem, Upgrade your software first
There are constantly something new and interesting coming out of this project so stay current if you can 

The FASTEST WAY to learn PySimpleGUI is to begin to play with it, and to read the documentation.
http://www.PySimpleGUI.org
http://Cookbook.PySimpleGUI.org

The User Manual and the Cookbook are both designed to paint some nice looking GUIs on your screen within 5 minutes of you deciding to PySimpleGUI out.

"""
    Welcome to the "core" PySimpleGUI code....

    It's a mess.... really... it's a mess internally... it's the external-facing interfaces that
    are not a mess.  The Elements and the methods for them are well-designed.
    PEP8 - this code is far far from PEP8 compliant. 
    It was written PRIOR to learning that PEP8 existed. 

    I'll be honest.... started learning Python in Nov 2017, started writing PySimpleGUI in Feb 2018.
    Released PySimpleGUI in July 2018.  I knew so little about Python that my parameters were all named
    using CamelCase.  DOH!  Someone on Reddit set me straight on that.  So overnight I renamed all of the
    parameters to lower case.  Unfortunately, the internal naming conventions have been set.  Mixing them
    with PEP8 at this moment would be even MORE confusing.

    Code I write now, outside PySimpleGUI, IS PEP8 compliant.  

    The variable and function naming in particular are not compliant.  There is
    liberal use of CamelVariableAndFunctionNames.  If you've got a serious enough problem with this
    that you'll pass on this package, then that's your right and I invite you to do so.  However, if
    perhaps you're a practical thinker where it's the results that matter, then you'll have no
    trouble with this code base.  There is consisency however.  

    I truly hope you get a lot of enjoyment out of using PySimpleGUI.  It came from good intentions.

    Popup - Display a popup Window with as many parms as you wish to include.  This is the GUI equivalent of the
    "print" statement.  It's also great for "pausing" your program's flow until the user can read some error messages.

    :param *args: (Any) Variable number of your arguments.  Load up the call with stuff to see!
    :param title: (str)  Optional title for the window. If none provided, the first arg will be used instead.
    :param button_color: Tuple[str, str] Color of the buttons shown (text color, button color)
    :param background_color: (str) Window's background color
    :param text_color: (str) text color
    :param button_type: (enum) NOT USER SET!  Determines which pre-defined buttons will be shown (Default value = POPUP_BUTTONS_OK). There are many Popup functions and they call Popup, changing this parameter to get the desired effect.
    :param auto_close: (bool) If True the window will automatically close
    :param auto_close_duration:  (int) time in seconds to keep window open before closing it automatically
    :param custom_text:  Union[Tuple[str, str], str] A string or pair of strings that contain the text to display on the buttons
    :param non_blocking:  (bool) If True then will immediately return from the function without waiting for the user's input.
    :param icon: Union[str, bytes] icon to display on the window. Same format as a Window call
    :param line_width: (int) Width of lines in characters.  Defaults to MESSAGE_BOX_LINE_WIDTH
    :param font:  Union[str, tuple(font name, size, modifiers) specifies the font family, size, etc
    :param no_titlebar:  (bool) If True will not show the frame around the window and the titlebar across the top
    :param grab_anywhere: (bool) If True can grab anywhere to move the window. If no_titlebar is True, grab_anywhere should likely be enabled too
    :param location: Tuple[int, int]  Location on screen to display the top left corner of window. Defaults to window centered on screen
    :return: Union[str, None] Returns text of the button that was pressed.  None will be returned if user closed window with X
