/*
* An aperture macro defines a complex shape and is a list of aperture primitives.
* Each aperture primitive defines a simple shape (circle, rect, regular polygon...)
* Inside a given aperture primitive, a fixed list of parameters defines info
* about the shape: size, thickness, number of vertex ...
*
* Each parameter can be an immediate value or a deferred value.
* When value is deferred, it is defined when the aperture macro is instanced by
* an ADD macro command
* Note also a deferred parameter can be defined in aperture macro,
* but outside aperture primitives. Example
* %AMRECTHERM*
* $4=$3/2* parameter $4 is half value of parameter $3
* 21,1,$1-$3,$2-$3,0-$1/2-$4,0-$2/2-$4,0*
* For the aperture primitive, parameters $1 to $3 will be defined in ADD command,
* and $4 is defined inside the macro
*
* Each basic shape can be a positive shape or a negative shape.
* a negative shape is "local" to the whole shape.
* It must be seen like a hole in the shape, and not like a standard negative object.
