/*
* Items use coordinates.
* A coordinate is defined relative to a page corner
* A coordinate is the X pos, the Y pos, and the corner which is the coordinate origin
* the default is the bottom right corner
* example: (start 10 0 ltcorner) or (start 20 10)
* The direction depends on the corner: a positive coordinate define a point
* from the corner origin, to the opposite corner.
*
* Items are defined by a name, coordinates in mm and some attributes,
* and can be repeated.
* for instance (repeat 2) (incrx 2) (incry 2) repeat the item 2 times,
* and coordinates are incremented by 2 on X direction, and 2 on Y direction
* Comments are allowed. they are inside (), and start by the keyword comment
* example:
* (comment rect around the title block)
*
* Lines and rect are defined by 2 coordinates start and end, and attributes.
* Attributes are linewidth and repeat parameters.
* example:
* (line (start 50 2 ltcorner) (end 50 0 ltcorner) (repeat 30) (incrx 50) )
* (rect (comment rect around the title block) (linewidth 0.15) (start 110 34) (end 2 2) )
*
* Texts are defined by the text (between quotes), the position, and attributes
* example
* "(tbtext \"1\" (pos 25 1 lbcorner) (font (size 1.3 1.3)) (repeat 100) (incrx 50) )"
* the text can be rotated by (rotation <value>) with value = rot angle in degrees
* (font (size 1.3 1.3) bold italic) defines a specific size,
* with bold and italic options
* (justify <justif keyword>) controls the text justification (the default is left)
* justif keyword is center, left, right, top and bottom
* (justify center top) is a text centered on X axis and top aligned on vertical axis
* The text size can be constrained:
* (maxlen <value>) and (maxheight <value>) force the actual text x and/or y size to be
* reduced to limit the text height to the maxheight value,
* and the full text x size to the maxlen value.
* If the actual text size is smaller than limits, its size is not modified.
