An EditEngine can have multiple paragraphs in it, nStartPara and
nEndPara are just the paragraphs the selection starts and ends in and
nStartPos and nEndPos are the character offset of the selection within
the start and end paras, so with an EditEngine of just one paragraph
with text "fooXbar" an ESelection of (0, 3, 0, 4) selection denotes the
selection of "X".
