Since iOS 13, the cascade list for the default UI font contains
meta-families for several writing systems, such as CJK. Since
these font families were never populated to the database, we ignored
them in Qt, and thus got missing glyphs for the characters in question.
The fix is to make sure these fonts are populated in the database.
It contains a partial backport of 922d195020,
which adds the qt_isFamilyPopulated() accessor to allow us to check
if the family has been populated in the font database. In Qt 5.14,
there is public API for this in QPlatformFontDatabase, so this is
a temporary resolution until then.

Those values must be scaled to device coordinates - otherwise borders,
margins etc. will be too small when rendered on high dpi devices
(printers etc.).
This change will add the scaling to those values.
QTextDocument::print applies 2cm margins to the root frame of a
unpaginated QTextDocument. Those margins were previously scaled to
device coordinates in order to give the correct result. But because
scaling is now done inside QTextDocumentLayout that scaling must be
removed and pixel values based on qt_defaultDpi are provided instead.

Notes:
The QTextDocument table model is much simpler than the HTML table model.
It basically only has <table> and <td> support. So the HTML parser is
forced to map markup and styling to the QTextDocument model which
is not without loss.
In other words: While QTextDocument -> HTML -> QTextDocument should
preserve the QTextDocument structure, HTML -> QTextDocument -> HTML
does not preserve the HTML DOM at all.
So for now the HTML importer and writer only support border styles on
the <td> and <th> nodes. In future updates, the HTML parser might be
enhanced to map <tr> and <table> CSS styles to the cells.

When calling QTextDocument::clearUndoRedoStacks() with UndoStack,
there were two bugs: The first was that we were retrieving
the item at "undoState" and deleting this. This is actually the
upper limit of the for loop. If the stack does not contain any
redos, then it would be == undoStack.size() and we would assert.
If there were redos, then we would delete the item at undoState
multiple times (actually undoState times).
In addition, when the loop exited, we first removed the dangling
pointers using remove() and then there was a weird resize() to
the new size minus the old undoState.
This would either assert because we tried to resize to a negative
number, or it would arbitrarily remove items from the stack.

Color fonts may also contain regular alphabet characters that
should be rendered with the current pen. In Qt, however, these
characters were drawn into the cache with a default pen color
of black.
Since all characters in a font is currently backed by the same cache,
and it would require a lot of plumbing to get around this, a step
in the right direction is to include the current pen color in the
cache as long as it is an RGB cache. This means that drawing
text with the color font with different pen colors will create
different caches.
There is no API to select font color on Freetype currently, but
this problem has also not been observed there, as the fonts
in question, with both regular and color glyphs, are not being
detected as color fonts (so the text color will be correct).
So Freetype will be left out for now.

Since it was added in Qt 4.2, addAppFont() has been written
to first register the font, then immediately invalidate the
font database and later reload the font again the next time
the db is used. This caused all application fonts to be
reloaded *at least* once, an operation which can be quite heavy
for large fonts, such as CJK fonts. If an application loaded
multiple fonts at different stages of execution, you could
end up loading the same fonts a large number of times, since
all application fonts would be reregistered every time a new
one was added.
When calling removeApplicationFont(), this is okay-ish, since
we need to remove all traces of the font from the platform
database and clearing the whole thing is a convenient way
of making sure there is nothing left. There might be more
efficient ways of doing this, but unloading fonts is not
a common operation, so it is fine to keep this behavior there.
This change removes the invalidation of the font database from
addAppFont(), since this should not be necessary as long as we
are adding fonts. It also removes the reregisterAppFonts flag,
which was a bit of a convoluted way of saying that the database
had been invalidated and needed repopulating. Instead, we use the
same mechanism as for repopulating the system database: We just
check if it is currently empty, which means it has been
invalidated and the application fonts have to be reregistered.
It does not touch the logic in qt_cleanupFontDatabase(), which
is kind of broken (it will leave application fonts in memory
and reregister them if the application continues to run). But
this is only actually called during shutdown (from application
destructor).

would be parsed multiple times, causing some unnecessary overhead
