Since the comma character was originally used as a separator, we
need to extend QFont to have setFamilies() so that we can avoid
joining the family strings together. This enables us to see the
family name as a single string and for multiple family names,
we have families().
Subsequently, this has added functions to QTextCharFormat to
account for multiple font families too. So it is now possible to
set a single one directly with setFontFamily() and multiple ones
with setFontFamilies().
This also bumps up the datastream version to 19 as QFont now
streams the families list as well.
[ChangeLog][QtGui][QFont] Add setFamilies()/families() to aid using of font families with commas and quotes in their name.

When showing a condensed font with AnyStretch, we should
not apply any stretch to the font (and if a stretch is
requested, we should calculate the actual stretch based
on how much the font is already stretched or condensed).
This usually works as expected, however, when using
QFont::NoFontMerging as the style strategy, we would
scale the glyph advances by the stretch of the font
since the calculated stretch of the font engine would
be overwritten by the actual stretch. In the case where
we use font merging, this would be done for the multi
engine, so we would not get the same issue, since the
text engine gets the stretch from the actual font engine
and this still has the original, calculated stretch
set.
Note on the test: We can't use testString() for this,
since it contains a space, and the test font does not
have a glyph for this, so we will end up merging a
different font for the space, giving us a slightly
different advance.

When we request fallback fonts, we cannot discriminate the fonts
based on the writing system support. This is especially important
since common script is now merged with other scripts, meaning that
a common script character will always go through the fallback
mechanism when not supported by the main font. When drawing
for instance a string of Devanagari characters on macOS, we would
get a list of 33 fallback fonts, but almost all of them would be
the default Devanagari font, since none of the other fallbacks
would support that script. Meaning that we would just check the
same font over and over, which makes no sense. The fallback list
has been retrieved specifically for the given script, so we do
not need to consider that when fetching the fonts.
For most of the common set, we will not have noticed the bug,
because at least one of the writing system-specific fallbacks will
have had support for latin characters as well. But when trying to
mix emojis and some non-common script, we would get a box in
place of the emoji, which had been adopted to the main script and
would only be looked for in the fonts supporting this.
Note that this exposed an issue with the QRawFont test on some
systems. When the sample text contained a space, it would
be possible to get a fallback font for this character, since
we now effectively support fallbacks. This is not the correct
behavior, but it is unrelated to this fix, and it was not what
the QRawFont::unsupportedWritingSystem() test was written to
check. I have therefore removed the space from the sample text
to make the test pass, and will make a separate task of fixing
the issue of merging fonts for whitespace characters.

Can now detect nested quotes and code blocks inside quotes, and can
rewrite the markdown too.
QTextHtmlParser sets hard-coded left and right margins, so we need to do
the same to be able to read HTML and write markdown, or vice-versa,
and to ensure that all views (QTextEdit, QTextBrowser, QML Text etc.)
will render it with margins. But now we add a semantic memory too:
BlockQuoteLevel is similar to HeadingLevel, which was added in
310daae539 to preserve H1..H6 heading
levels, because detecting it via font size didn't make sense in
QTextMarkdownWriter. Likewise detecting quote level by its margins
didn't make sense; markdown supports nesting quotes; and indenting
nested quotes via 40 pixels may be a bit too much, so we should consider
it subject to change (and perhaps be able to change it via CSS later on).
Since we're adding BlockQuoteLevel and depending on it in QTextMarkdownWriter,
it's necessary to set it in QTextHtmlParser to enable HTML->markdown
conversion. (But so far, nested blockquotes in HTML are not supported.)
Quotes (and nested quotes) can contain indented code blocks, but it seems
the reverse is not true (according to https://spec.commonmark.org/0.29/#example-201 )
Quotes can contain fenced code blocks.
Quotes can contain lists. Nested lists can be interrupted with
nested code blocks and nested quotes.
So far the writer assumes all code blocks are the indented type.
It will be necessary to add another attribute to remember whether the
code block is indented or fenced (assuming that's necessary).
Fenced code blocks would work better for writing inside block quotes
and list items because the fence is less ambiguous than the indent.
Postponing cursor->insertBlock() as long as possible helps with nesting.
cursor->insertBlock() needs to be done "just in time" before inserting
text that will go in the block. The block and char formats aren't
necessarily known until that time. When a nested block (such as a
nested quote) ends, the context reverts to the previous block format,
which then needs to be re-determined and set before we insert text
into the outer block; but if no text will be inserted, no new block
is necessary. But we can't use QTextBlockFormat itself as storage,
because for some reason bullets become very "sticky" and it becomes
impossible to have plain continuation paragraphs inside list items:
they all get bullets. Somehow QTextBlockFormat remembers, if we copy it.
But we can create a new one each time and it's OK.

"When Korean uses SPACE for line breaking, the classes in rule
LB26, as well as characters of class ID, are often tailored to AL"
When using Qt, the user would expect the WordWrap wrap mode to
break between words in Korean. If you want the syllable-based
text layout, you would use WrapAnywhere, probably accompanied
by line justification.
To avoid breaking QTextBoundaryFinder and other potential clients

This led to a mismatch between the vector and the hash (given that the hash

Spotted by interrupting kmail in gdb, and it was in this code
iterating over a 2000 entries hash (the first vector entries not matching

When calculating the width of a text for drawing decorations on top,
we use the effective advance of the whole text after it has been
through the shaper.
However, in the case of QStaticText and QGlyphRun, there is shortcut:
Since we only have the glyph indexes and position of each glyph,
we use the position + advance of the right-most glyph to find the
right-most edge of the decoration. For this, however, we use the
advance of the glyph *out of context* of the rest of the string,
because the whole idea is to avoid doing the shaping of the string
with every draw call. In some rare cases, the advance of the
right-most character, in the context of the string, is different
from the advance of the standalone glyph.
Now, one way of fixing this would be to store the width of the
text in QStaticText and QGlyphRun, but since it is a very rare
artifact which is barely visible, I have opted to just work around
it in the test instead, the workaround being to force integer
metrics so that we don't get the small 0.2 pixel error.

Private Use Area characters are quite valid input characters when used
in combination with a custom font. Joiners also serve an important language
purpose in semitic writing systems.
Note that there is a hack where we disregard any character produced
using CTRL or CTRL+SHIFT specifically because of German keyboards. I have chosen to
keep the hack in this patch to limit the change (though I have made an exception
for ZWJ and ZWNJ since both are produced using Ctrl+Shift on Windows), but it
will probably have to be reverted.

Commit 2bc7a40048 taught the CoreText font database to populate the
families lazily, and in the process added a guard to ensure that we
didn't populate internal fonts (prefixed with a '.'), as these fonts
would then show up in font selection dialogs.
Commit 909d3f5c7 then added support for private fonts, by making it
possible to filter out any private fonts from font selection daialogs.
But the guard was not removed, so we were still not populating these
fonts. This guard has been removed, and the filtering function has
been updated to include the conditions of the guard.
Next, commit e5e93345c5 used [UIFont fontNamesForFamilyName:] to verify
that each family that we registered with the font database would also
have matching fonts when finally populated. This is not the right approach,
as [UIFont fontNamesForFamilyName:] does not handle internal fonts.
Instead we trust what CTFontDescriptorCreateMatchingFontDescriptors()
gives us, but make sure to register the resulting font descriptors
with the original/originating font family, instead of the one we pull
out of the font descriptor.
Finally, as of iOS 10, we can use CTFontManagerCopyAvailableFontFamilyNames
instead of [UIFont familyNames], which gives us all of the internal font
families like on macOS, instead of just the user-visible families. For
earlier iOS versions we manually add '.PhoneFallback', as we know it
will be available even if not listed in [UIFont familyNames].
The end result is that we register and populate families like '.PhoneFallback',
which is critical to supporting more esoteric writing systems.
The check in tst_QFont that styles for a given family is not empty has
been removed, as we can't guarantee that on all platforms, which is
also documented for QFontDatabase::styles().

No-break-spaces should not be counted in the space data, but rather
be treated as any other non-breakable character. We were already
taking care of this in the loop we reach if the item starts with
a character which isn't whitespace, but there is a second loop for
items that begin with whitespace characters.
The result of this was that in certain circumstances where you gave
the nbsp its own format and made the line wrap, the previous line
would count an extra trailing space and it would swallow the first
character in its following line.

We were throwing away important information by claiming that all
fonts support all the standard sizes in QFontDatabase on Windows
This caused the font dialog to list unsupported sizes for bitmap
fonts, unlike the native font dialog.
We would also claim to support creating bitmap fonts at
unsupported sizes, which would lead to
1. QFontInfo(font).pointSize() would return the requested size,
not the actual rendered size.
2. Bitmap fonts created at 64 pixels and higher would be invisible.
On Mac, there are no system bitmap fonts, and the use is not very
common, but installing some bitmap fonts on the system, it does
seem to ignore the sizes supported in the font and just displays
the standard list instead, so we keep the current behavior there.
