for the upstate (when the mouse is not over the button), the overstate,
and the downstate. For example, you may want to show your menu
using Arial font with no underlines until a user rolls his or her mouse
over a button. The other modifiable style in the SimpleMenu class is
the rectangle that is drawn behind the text of each button. You can
control the opacity of the rectangle in the different states with the
backgroundUpAlpha, backgroundDownAlpha ,and backgroundDownAlpha
properties to have it semi see-through (or set their value to 0 and get
rid of the rectangle altogether). Additionally, you can control the color
of the rectangle separately for each state as well. Once the Simple-
Menu class is used to create a menu in your project, you can assign
any function to any button within that menu by using the assign
Action method.
