21    Mostly, we *don't* want to pass both the height and width of the text
22    to the text rendering routine. We just want to prescribe the height,
23    the width being determined accordingly.
24    
25    The height needs to be passed in a coordsys to enable interpolation
26    (very desirable). Also, the origin of the text, and the direction.
27    
28    The solution is to pass these three (origin, direction, height)
29    in one coordinate system and the "aspect ratio" in another.
30    
31    Thus:
32    
33  Two coordinate systems are passed. The second will correctly default to zero.  Two coordinate systems are passed. The second will correctly default to zero.
