UT_sint32 fb_LineBreaker::breakParagraph	(	fl_BlockLayout *	pBlock,
		fp_Line *	pLineToStartAt,
		fp_Page *	pPage
	)

Break paragraph of text into lines

Parameters:

pBlock

Paragraph (block) of text

Returns:: 0

LineBreaker shouldn't break a line until it finds a non-blank item past the end of the line. All trailing spaces should remain on the end of the line.
