But in order to assume this you already assume that (a) text characters are
internally presented by the same primitive as other objects and (b) that
characters are converted to 3d shapes before being rendered.  Both assumptions
are incorrect.

There is no "little error is added to the z component of every control point"
as the source code (of 3.1 for you right now, but nothing changed in 3.5)
clearly shows.

As I have pointed out numerous times before, this is simply a precision error
no matter how much you or others test your "theory", looking at the "fact" -
the source code - easily proves your "theory" wrong.
