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.

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().

The extension vector for this class calls for additional
properties to be added later, but these are not user-
settable. It thus suffices to rely on the only data
member, a qint64, which can be reinterpreted to an index
into an array or hash with actual objects. This allows
to make the class a Trivial Type (ie. no overhead over
an int) while still supporting later extension. Cf.
QSslEllipticCurve as another example of such a class.
The extension has to maintain the following invariants,
encoded into user code by way of being used in inline
functions:
- m_numericId == -1 <=> !isValid()
This is trivial to support. An extension could not and
still cannot reinterpret the qint64 member as a d-pointer,
but a d-pointer is only necessary for user-settable
properties where updating a central private data structure
would cause too much contention.
Add a test.
Since this type is used in other modules, keep the existing
functions, but mark them as deprecated with the expectation
that these compat functions be removed before 5.8.0 final.

We parse the EXIF header in order to get the proper orientation, so
let's be a bit more careful in what we accept. This patch adds better
handling for reading past the end of the stream, plus it limits the
number of IFDs read (to avoid processing too much data) and deals with a
pathological case of the EXIF file format: EXIF (due to its TIFF
origins) permits the offset to the next IFD to be backwards in the file,
which means it could result in a loop or pointing to plain corrupt data.
We disallow any backwards pointers, since it seems that's what other
decoders do (libexif, for example).

Turns the two set of tables in QDrawHelperGammaTables into two
QColorProfile classes that use similar structures and can be reused for
other gamma correction.
At the same time clean-up and improve the comma-correct blending code
to use the new profiles and QRgba64 precision.

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.

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.
[ChangeLog][QtGui][Text] Fixed a bug where a no-break space would
sometimes cause the first character of the containing line to not be
displayed.

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.
[ChangeLog][QtGui][Text] Fixed list of supported sizes for
bitmap fonts on Windows.
