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