pdfGetHTMLTextWidth

Purpose — Measure the natural (unwrapped) width of HTML at Size — the width of its widest line with no wrap constraint.

Description — Calls RenderHtml with Width=0 (no wrap) and Measure=True (no drawing); returns the resulting natural width. Because there's no wrap width, this reports the width of the single widest hard-break segment, not a wrapped-paragraph width.
