dlpdfcontenttextwidth
This procedure is included as an aid to composition, and to transforming widths,
particularly word space widths, into PDF units. The procedure will return the width
(in points) of the specified text.
Its calling parameters include:
• the specified Font
• the text to be measured
• its current SetWidth (horizontal point size)
• Current Text State, a pointer to a PDETextState structure, which may be
