Since Windows 10 update 1809 it is possible to install fonts as a user
so they are only available for use by the user and not on the system.
So this location in the registry needs to be checked as well when

This was added as a platform-specific implementation of the multi engine
in 2005, before this code was generalized, and it currently only has the purpose
of special handling loadEngine().
The way this was special handled was by creating a new QFontEngine for every
fallback family *every* time, never checking if the font engine already exists
in the cache (like the superclass implementation does). The result of this was
that if you had 500 fonts and each of them had 500 fallback fonts, and made
a loop that would load all of them, then you would get 250000 font engines.
At some point before this, we would run out of available handles and crash.
There shouldn't be any need to have special handling of fallback font loading
on Windows (i.e. all the platform specific parts should go through the normal
mechanisms in QPA), so lets just go through the superclass implementation instead.
[ChangeLog][Windows][Text] Reduced the number of font engines that are
created when loading new fonts, fixing crashes in some special cases where
a large number of fonts are created during a short period of time.

The function doesn't need the flags argument, nor does it need the
ctfont or fontdef arguments if it's a normal const member function.
It can also be used from QCoreTextFontEngine::stringToCMap(), instead
of duplicating the code. This was originally the case before b4aa5d97
which improved surrogate pair handling, but for some reason the change
introduced the duplicate code instead of just changing the arguments
in the function call slightly.
The use of 0xff000000 to skip certain glyphs looks dubious, and is
probably related to QFontEngineMulti's use of the high byte to
indicate which engine the glyph came from, but the multi engine
strips this away before calling out to the concrete engine so
it could potentially be removed in a later patch.

On later versions of macOS, the font weight trait of fonts is a 64 bit
double, not a 32 bit float, and on macOS 10.14, CFNumberGetValue()
started returning false for values when the type conversion is lossy,
like it is documented to. Therefore, we would end up without weight
information in 10.14.
The fix is to ask for a double instead, which works regardless of
whether the CFNumber represents a 32-bit or 64-bit value.

macOS 10.14 uses a new font smoothing algorithm that takes the fill color into
account. This means our default approach of drawing white on black to produce
the alpha map will result in non-native looking text when then drawn as black
on white during the final blit. As a workaround we use the application's current
appearance to decide whether to draw with white or black fill, and then invert
the glyph image in the latter case, producing an alpha map. This covers the
most common use-cases, but longer term we should propagate the fill color all
the way from the paint engine, and include it in the key for the glyph cache.
At the moment we do not react to changes in the application appearance,
as that seems to be buggy in general in Qt (palette/style, e.g.), and those
bugs need to be weeded before we can react to the theme change with confidence.
