line-paragraph

Returns the paragraph number of the paragraph containing the line. Lines are numbered starting with 0. Paragraphs are numbered starting with 0.

Calling this method may force the recalculation of location information if a maximum width is set for the editor, even if the editor currently has delayed refreshing (see refresh-delayed?). If the editor is not displayed and the editor has a maximum width, line breaks are calculated as for line-start-position.
