How is the line distance in PDF multiline text form fields controlled?
The text leading operator (TL) seems to be ignored, if placed within the DA
(default appearance) property of the widget annotation dictionary.
The same applies for rich text fields, when using the DS (default style) attribute.
If a "line-height:18pt" is placed there, it is also ignored (although this is a not documented
CSS attribute in the PDF specification, it is a valid style attribute).
Is there any way to have a multiline text field with a programmed line distance?
