43 /* gerber files have different parameters to define units and how items must be plotted.
44  * some are for the entire file, and other can change along a file.
45  * In Gerber world:
46  * an image is the entire gerber file and its "global" parameters
47  * a layer (that is very different from a board layer) is just a sub set of a file that
48  * have specific parameters
49  * if a Image parameter is set more than once, only the last value is used
50  * Some parameters can change along a file and are not layer specific: they are stored
51  * in GERBER_ITEM items, when instancied.
52  *
53  * In GerbView, to handle these parameters, there are 2 classes:
54  * GERBER_FILE_IMAGE : the main class containing most of parameters and data to plot a graphic layer
55  * Some of them can change along the file
56  * There is one GERBER_FILE_IMAGE per file and one graphic layer per file or GERBER_FILE_IMAGE
57  * GerbView does not read and merge 2 gerber file in one graphic layer:
58  * I believe this is not possible due to the constraints in Image parameters.
59  * GERBER_LAYER : containing the subset of parameters that is layer speficic
60  * A GERBER_FILE_IMAGE must include one GERBER_LAYER to define all parameters to plot a file.
61  * But a GERBER_FILE_IMAGE can use more than one GERBER_LAYER.
