Abdelrazak Younes eed6514dd0 Move selection painting closer to row painting. Single row painting is now possible for selection.
* 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.
