- getFont() becomes TextMetrics::getDisplayFont()
- setCharFont() now needs a display font.
- setInsetFont() and setFont() now needs a BufferView, will be transferred to TextMetrics too.
- isRTL(): moved to TextMetrics
- isRTLBoundary(): ditto
- font_: ditto

* BufferView::draw(): makes use of PainterInfo::full_repaint
* TextMetrics::drawParagraph(): ditto.
* InsetText::drawSelection(): don't fillRectangle() if there's no selection.

^ Row:
- changed_: new boolean to inform change status at draw time.
- crc_: new crc_ signature
- inline pos() and endpos()
- replace width(), ascent() and descent() direct access with dimension().
* ParagraphMetrics
- do not maintain row_signature_ anymore
- rename calculateRowSignature() to computeRowSignature() and make it public
* TextMetrics
- redoParagraph(): don't clear the ParagraphMetrics row list, reuse and update it.
- rowHeight(), rowWidth(), rowBreakPoint(): take first/end positions instead of Row.

- move RowPainter class out of the anonymous namespace so that it can be used by TextMetrics::drawParagraph().

On fullscreen redraw the metrics of all visible paragraphs are
recreated and stored in the TextMetrics object. If the number of
paragraphs on screen does not change everything is fine because the
paragraph metrics cache is just updated. But if the number decreases
it can happen that old paragraph metrics remain in the cache. If this
happened because e.g. a paragraph was deleted, it's possible that the
cached paragraph is longer than the one which is actually at the
position now. Using the Row objects from the cached paragraphs then
can trigger accesses to positions which would have been valid in the
old paragraph, but go over the end of the paragraph which is there
now.
