/**
* Window displaying the cargo connections around an industry (or cargo).
*
* The main display is constructed from 'fields', rectangles that contain an industry, piece of the cargo connection, cargo labels, or headers.
* For a nice display, the following should be kept in mind:
* - A #CFT_HEADER is always at the top of an column of #CFT_INDUSTRY fields.
* - A #CFT_CARGO_LABEL field is also always put in a column of #CFT_INDUSTRY fields.
* - The top row contains #CFT_HEADER and #CFT_SMALL_EMPTY fields.
* - Cargo connections have a column of their own (#CFT_CARGO fields).
* - Cargo accepted or produced by an industry, but not carried in a cargo connection, is drawn in the space of a cargo column attached to the industry.
* The information however is part of the industry.
*
* This results in the following invariants:
* - Width of a #CFT_INDUSTRY column is large enough to hold all industry type labels, all cargo labels, and all header texts.
* - Height of a #CFT_INDUSTRY is large enough to hold a header line, or a industry type line, \c N cargo labels
* (where \c N is the maximum number of cargoes connected between industries), \c N connections of cargo types, and space
* between two industry types (1/2 above it, and 1/2 underneath it).
* - Width of a cargo field (#CFT_CARGO) is large enough to hold \c N vertical columns (one for each type of cargo).
* Also, space is needed between an industry and the leftmost/rightmost column to draw the non-carried cargoes.
* - Height of a #CFT_CARGO field is equally high as the height of the #CFT_INDUSTRY.
* - A field at the top (#CFT_HEADER or #CFT_SMALL_EMPTY) match the width of the fields below them (#CFT_INDUSTRY respectively
* #CFT_CARGO), the height should be sufficient to display the header text.
*
* When displaying the cargoes around an industry type, five columns are needed (supplying industries, accepted cargoes, the industry,
* produced cargoes, customer industries). Displaying the industries around a cargo needs three columns (supplying industries, the cargo,
* customer industries). The remaining two columns are set to #CFT_EMPTY with a width equal to the average of a cargo and an industry column.
