* Row: - setSelection(): set selection begin and end for this row. - sel_beg, sel_end: new public members. * BufferView::draw() - do not trigger a full repaint for selection. - use TextMetrics::draw() instead of hand calling TextMetrics::drawParagraph(). * InsetText::draw(): don't call TextMetrics::drawSelection(). * InsetMathMBox::drawSelection(): remove. * TextMetrics: - drawSelection(): simplify a bit. Now private. - redoParagraph(): memorize Row selection status. - x2pos(): fix crash when selecting with PageDown. - draw(): fill-in the ParPos cache before everything else and not in drawParagraph(). - drawParagraph(): take care of row selection painting. git-svn-id: svn://svn.lyx.org/lyx/lyx-devel/trunk@20066 a592a061-630c-0410-9148-cb99ea01b6c8
