Overview
-----------------------------------------------------------------------------
When the Choices window is displayed, this adds a window displaying the description set for each choice.

The description is created using the Comment Event's Contents.
If the first line of the Comment contains <SHW_Description>, the text on subsequent lines will be used as the description.

Create the event as follows:

◆ Show Choices: Yes, No (Window, Right, #1, #2)
: Yes
◆ Comment: <SHW_Description>
: Description when "Yes" is selected
◆
: No
◆ Comment: <SHW_Description>
: Description when "No" is selected
◆
: End

The description window is fixed at the top of the screen.
Up to two lines of description can be displayed.
