Show a "Notification Window"

This is a very clever bit of code that was submitted by a PySimpleGUI user. It shows a "toaster" style of window (doesn't slide up/down but instead fades in/out). You can click on the notification window and it will immediately dismiss it.

The fade-in/fade-out effects are not visible on Trinket but are if you download the code and run on your computer.

This program demonstrates:

• Computing screensize for placement of window
• Using a no_titlebar setting to create a clean window that doesn't look like a "normal window"
• Alpha channel used to fade window in and out
• Embeds icons into the code itself thus removing the need for multiple files. Makes it possible to copy and paste the program into your code to add the feature.
• Use of Element.Widget member variable to extend the PySimpleGUI feature set by directly accessing a tkinter setting. Used to create the "hand" cursor when mouse is over window
• Using a single Graph Element to draw an entire window, placing graphics and text in a very precise manner. The entire window is a single Graph Element
