* This is a bit complicated due to cumulative calculations:
* - numerous cases (mirrored or not, rotation)
* - the DrawGraphicText function recalculate also H and H justifications according to the
* text orientation.
* - when symbol is mirrored, the text is not mirrored and justifications are complicated
* to calculate so the easier way is to use no justifications (centered text) and use
* GetBoundingBox to know the text coordinate considered as centered
