What does the "tap illustration" option do?

Taplist.io has built-in illustrations for draft beverages (i.e. keg taps), and many themes make use of these.

You can configure each tap to be illustrated in one of the following ways:

• Show as keg: A keg shell matching the beverage color, or an empty shell if there is no beverage, will be shown. This is the default.
• Show as glassware: Glassware matching the beverage's glassware style and color, or an empty shaker pint glass if there is no beverage, will be shown.
