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.

Certain fonts with multiple styles have the same family name. When
loading these as application fonts we were not specific enough when
querying for the text metrics. This meant that e.g. the bold version in
a font family would get the metrics of the regular one.

In ff2ae36551b75b2c8a2d1f73e4d1e956b4eadb62 we added support for
the End User Defined Characters font when it is available, and
it was added as the first fallback font to avoid being overridden
by a symbol font.
An unintended side effect was that we would also override the
default fonts for the selected style hint, so in e.g. the textedit
example, all the text would default to EUDC. We now add it after
the default style hint font instead. We also mark it as a
private font family, since it should not be shown in the font
combo box as a selectable font, but should only be used automatically
as fallback for PUA characters.

EUDC, or "End-User Defined Characters", is a concept in Windows,
where the end-user can create a local fallback font of default
glyphs for the PUA (Private Use Area, a range of Unicode
not reserved to any writing system), and these glyphs will be
used when displaying the character using a font which does not
itself support the code point.
To support this in Qt we look up the default EUDC font in the registry
and add it to the fallback fonts if it is available. We use the
font for code page 1252. This has been tested on a couple of systems,
and appears to always be present. The font is added to the front of
all fallback lists, so that it will override other fallbacks,
such as Segoe UI Symbol, which happens to assign glyphs to the PUA.
If there is no end-user defined fallback, then Segoe UI Symbol will still
be used as before.
Note that this required a small change in the code to get canonical
font names. The EUDC font that Windows generates will only have a
name set for the current locale, and we expected all fonts to have
an English name. Instead, the code has now been changed to prefer
the English name if one is present, but accept any other name if
there is nothing in English.
[ChangeLog][Windows][Text] Added support for End-User Defined Characters
in Qt.

Looks up the canonical names of enumerated fonts and register them under
their preferred names if present.
Also changes the logic handling registration of english aliases, so it
is always done, even if it might in rare cases cause a double
registration since that is safe.

This allows creating or extending QPA plugins to provide access to QFont
and related types.
It concerns both GDI and DirectWrite engines, as well as the regular and
the freetype based font databases. The qt.qpa.fonts logging category has
been moved together into the QWindowsFontDatabase related files to avoid
depending on the qwindowscontext.h header file. Finally, QwindowsNativeImage
is following pending a future refactor with similar code in qpixmap_win.cpp
and the Windows XP style.
