* scaling in play, then the scaling is taken into account during path
* construction (when rendering) and when the path is stroked the stroke
* width remains the same. However if we capture the path in pdfwrite as
* a font, the scaling is applied after the glyph is drawn, and this
* results in the stroke width being anamorphically scaled as well, which
* is wrong. In this case we want to be able to avoid capturing the text
* as a font and instead draw a path and stroke it. Previously the stick
* font was just a ft_user_defined but this allows us to tell the
* difference.

* as required. However pdfwrite needs to know that this is not a regular
* type 3 font, otherwise it won't know to look out for the cache entry
* being freed, and will reuse the original definition
