[VXA] Item Icon List 1.0.2

#==============================================================================
#    Icon Item List
#    Version: 1.0.2
#    Author: modern algebra (rmrk.net)
#    Date: 16 June 2013
#++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
#  Description:
#
#    This script changes the item window so that it shows only icons to
#   represent the item and a number to show how many are held.
#++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
#  Instructions:
#
#    Paste this script into its own slot in the Script Editor, above Main but
#   below Materials.
#
#    You can also customize the size of each icon space, as well as various
#   aspects of the font to draw the number, including size, colour, and whether
#   it is bolded. As well, you can set it so that the name of the item shows up
#   in the help window, and you can set its format as well. To do so, go to the
#   Editable Region at line 53 and read the instructions contained there.
#
#    The script also allows you to set it so that each icon has a background
#   colour and a shadow. Those are set at lines 90-95. You can also set it so
#   that each item has its own background colour by using either of the
#   following codes in its notebox
#
#      \back_colour[x]
#      \back_colour[r, g, b, a]
#
#    If the former, the xth colour on the windowskin palette will be used. If
#   the latter, then it will choose a colour with those rgb and alpha values.
#
#    Note: using the Name feature will reduce the amount of space you have for
#   the actual description of your items. By default, it takes a whole line
#   (although you can change that by altering the NAME_FORMAT string). If that
#   is a problem, you could turn the feature off (but then it would not show
#   the name anywhere). Another solution would be to increase the size of the
#   help window. That can be done by using my Customizable Item Menu script,
#   which you can find here:
#
#      http://rmrk.net/index.php/topic,46516.0.html
#
#   If you use the Image in Description feature, you should probably remove the
#   \\icon from the NAME_FORMAT at line 112.

  SPACING = 12       # The space between icon slots
  # Number Settings
  #  NUM_FONTNAME - The font for the numbers. It should be an array of strings,
  # with each string being a font name ranked by priority. It will use the
  # first font in the array that exists on the user's computer. It will use
  # the default if set to nil.
  NUM_FONTNAME = nil

  NUM_SHADOW = true  # Whether the number of items should have a shadow
  NUM_OUTLINE = true # Whether the number of items should have an outline
  NUM_ALIGN = 2      # Alignment of number. 0 => Left; 1 => Centre; 2 => Right
  DO_NOT_DRAW_NUM_IF_1 = false # Don't draw num if only possess 1 of item
  # Colours
  #  Each of the colour settings can be either an integer, an array, or a
  # Color object. If an integer (0, 1, ..., 31), it will take its colour from
  # that index of the windowskin's colour palette. If an array, then it must
  # be in the form: [red, green, blue, alpha], where each is an integer between
  # 0 and 255. alphas is optional. Color objects may also be used, in which
  # case it is: Color.new(red, green, blue, alpha)
  #
  #  Examples:
  #    NUM_COLOUR = 0
  #    NUM_COLOUR_WHEN_MAX = [100, 200, 145]
  #    NUM_OUT_COLOUR = Color.new(75, 75, 75, 160)
  #
  #  If you set NUM_OUT_COLOUR to nil, then it will just use the default
  # outline colour.
  NUM_COLOUR = 0     # The colour of the number
  NUM_COLOUR_WHEN_MAX = 17 # The colour of the number if holding maximum
  NUM_OUT_COLOUR = nil # The colour of the outline, if showing. If nil, default
  # Back Settings
  #  These allow you to set a background colour for your items. The same
  # The same options for setting colours are available here as they are above.
  # Additionally, if set to nil, there will not be any colour.
  #
  #  If you do decide to use them, recommended values for each are:
  #    BACK_DEFAULT_COLOUR = Color.new(64, 64, 64, 160)
  #    BACK_SHADOW_COLOUR = Color.new(0, 0, 0, 128)
  BACK_DEFAULT_COLOUR = nil # Default Main Colour
  BACK_SHADOW_COLOUR = nil  # Colour of Shadow
  # Name Settings
  #  SHOW_NAME_IN_DESCRIPTION - Set to true if you want to show the name of the
  # item in the description window. Set it to false otherwise.
  SHOW_NAME_IN_DESCRIPTION = true
  #  NAME_FORMAT - This is the format of the name, if shown in the description
  # window. The code \\icon will be replaced with the icon of the currently
  # selected item, and \\name will be replaced with the name of the currently
  # selected item. All the other message codes are also recognized, but you
  # need to use two backslashes (\\), not one (\). Examples:
  #    Good:     \\c[16]
  #    Bad:      \c[16]
  # The code \n (one backslash) will make a new line.
  NAME_FORMAT = "\\icon \\c[16]\\name\\c[0]\n"
