Commit 8d354382a4 introduced a regression in RTL phrases display.
When an RTL line had trailing spaces we started displaying them in
front of the text still assuming counted line width value that did
not include those trailing spaces.
Line width is not including trailing spaces width because it is
allowed to fit in the line any number of spaces.
Also text block "left padding" entity was eliminated. If we have
some spaces in the start of the text block (for example a text block
after a link) we just add an empty word and mark those spaces as its
right padding.
- Use QPainter current pen for selected text in cases we
didn't specify it explicitly in the TextPalette.
- Better rounding of QRectF from QFixed values to QRect selected
background filling areas.
- Using QPainter::viewport() instead of random huge QRect() in
clipping, because it fails to apply this huge QRect() clip region
in Retina paint devices: 2x scale QMatrix::map() is not defined for
QRegion-s having rects with sum of dimensions larger than 100000.
