e6880e7cd1 Fix text shifting vertically when elided
When eliding text we would check for the existence of the ellipsis
character and fall back to using the dot if it was not available.
However, when font merging was in use, we would also use ellipsis
from a fallback font if available. This could cause the metrics
of the text to increase if the fallback font had larger metrics,
and the result was that text could shift when elided.

It is better to prefer the dot from the current font than to use
the ellipsis from a fallback, so we only use the ellipsis if
it is in the main font.

[ChangeLog][QtGui][Text] Fixed a bug where eliding text could
change the height of its bounding rectangle for certain fonts.

4d88d79aa5 Update usage of QFontMetrics::width() to new API
QFontMetrics(F)::width() has been deprecated and is replaced by
horizontalAdvance(). This updates all usage of it in tests and
documentation.

It is worth noting that many or most of the usages of
QFontMetrics::width() probably intended to use boundingRect().width(),
but since it currently works, I have not looked into that, just
replaced the function name mechanically.

ee2ad9df70 Add QFontMetrics(F)::horizontalAdvance() function
A source of constant confusion is the QFontMetrics::width() function,
which does not return the bounding width of the text, but the advance
width. We deprecate this and add horizontalAdvance() instead, to avoid the
confusion in the future.

Note that there was an internal width() overload which was only there
for the purpose of supporting the Qt::TextBypassShaping flag. This
flag has already been replaced by public API, so no such
overload is added. Instead, we deprecate the TextBypassShaping flag
as well, which makes sense, since a replacement has been made.

Also note that there was a consistency problem with QFontMetrics and
QFontMetricsF, which are supposed to be interchangeable. The
QFontMetrics::width() functions for strings took an optional int length
argument, while the floating point version did not. This error is
corrected in the advance() functions.

[ChangeLog][QtGui][Text] Added QFontMetrics::horizontalAdvance() and
QFontMetricsF::horizontalAdvance() to replace the confusingly named
width() function. The latter has now been deprecated.

73176d2922 Add API to disable text shaping on fonts
In the past, we had an undocumented text flag that worked with
one of the QPainter::drawText() overloads. This was never intended
as public API and served a specific cause in Qt WebKit at one point.

But there is a general need for such API, as disabling shaping features
easily gives 25% performance improvement on text rendering even for
fairly short strings.

This patch adds a new style strategy flag to disable shaping and
will just uses the CMAP and HDMX tables to get glyph indices and advances
for the characters. In Qt 6, the TextBypassShaping flag can be removed
completely and be replaced by the style strategy.

[ChangeLog][QtGui][Text] Added QFont::PreferNoShaping style strategy to support
improvements to performance at the expense of some cosmetic font features.

d641792ff2 Fix QFontMetrics width
Commit f4dd534 introduced a regression, so that QFontMetrics reported
a wrong size (to be more specific width) for FreeType fonts.
The calculation of glyph advances has to to reflect (rounded)
integral number of pixels. This was only done when the glyph was cached.
So in some cases the first call to QFontMetrics::size gave a different
result than the second.
This patch reverts f4dd5344fb.

The tst_QFontMetrics::same auto test only happened to work on some
platforms, on BlackBerry for instance it did not. Extended the test
case to make sure it works for different font sizes.

as a minor optimization some time later.

In order to preserve the existing behavior, we map all scripts up to Latin to Common.
