 Instructions:

 1) To show some text above an event, add a script command, saying:
    text = "place your text here"
    popup(text)

 2) To show an icon in the popup, add a script command, saying:
    text = "place your text here" *
    icon = "the icon's name" **
    popup(text, icon)

 3) To automatically get the icon of an Armor, Item, or Weapon
    replace the line saying 'icon = something', with:
    icon = get_icon(item_type, item_number) ***

    ie:
    icon = get_icon('Armor', 2)

 4) You can draw two lines of text, by using:
    line1 = "Headline"
    line2 = "some text"
    icon = "icon name"
    popup(line1, icon, line2)

    the 2nd line will have smaller font and a white color.
    it will be displayed above the first.
    if you don't want an icon, set it to: nil

 5) To set the font size, color and the window opacity
    as well as the time the popup stays on the screen,
    see line 95 and below.


   Notes:
   *   To show only an icon, set the text to ""
   **  The icon-name should not include ".png", ".jpg" etc.
   *** You can also use 'skill' and a skill number.
