/* Fields are texts attached to a component, having a special meaning
* Fields 0 and 1 are very important: reference and value
* Field 2 is used as default footprint name.
* Field 3 is reserved (not currently used
* Fields 4 and more are user fields.
* They can be renamed and can appear in reports
*/
/* set USE_TEXT_JUSTIFY_INITIAL_BEHAVIOR to 0 to use
* a justification relative to the text itself
* i.e. justification relative to an horizontal text
* or to 1 to keep the initial Eeschema behavior
* The initial behavior is:
* For vertical texts, exchange the horizontal and the vertical justification
* The idea is to keep the justification always left or top for instance,
* no matter the text orientation
* This is a bit tricky when you want to change a text field justification
* when the fiels and the component are both rotated 90.0 degrees
