This patch mainly do two things:
1) Support color bitmap font for freetype fontengine. This partially
based on Corentin Jabot's patch
2) Support ARGB opengl glyph cache when workaround_brokenFBOReadBack is
true (It is always true under Android). Some code refactor has been
done in QOpenGLTextureGlyphCache.
This patch also bump the minimal required freetype version to 2.2

Coverity, CIDs 10917, 10918. This fix looks like purely cosmetic
and unneeded: we check f->error() after f->open(). Unfortunately,
f->open() can fail without setting an error (if you provided an invalid mode).

Some color bitmap fonts will have a size greater than 127 pixels,
areMetricsTooLarge() will return true(its advance exceed 127) for
these fonts and we are unable to render these fonts since
QFontEngineFT::loadGlyph() will simply do nothing if
areMetricsTooLarge() return true. To support bitmap font whose size
is between 128 and 255, we change x,y,advance of QFontEngineFT::Glyph
to short variable to make areMetricsTooLarge() return false, in this
way we will be able to render such color bitmap fonts.

Always prefer the requested font, even if it doesn't support the
script of interest, and fallback to a font that *does* support that
script, so that the best-matching font always takes a precedence.
The result looks much closer to what CT and GDI/DW does.

These types are held in QVarLengthArrays, so benefit
from being trivially relocatable. They are also part
of the private API, so there's no BC issues with
potential uses of these types in QList, except for
QPainter::PixmapFragment, which consequently has been
marked as relocatable only.

The QTextBlockFormat::FixedHeight overrides the line height
regardless of its calculated height. If the line contains
objects or text which is higher than the specified line height,
using FixedHeight will cause them to overlap with the previous
line. This is not what happens in normal web browsers. The
expected behavior is that the line height given in CSS is the
minimum height, but that we still reserve space needed to display
everything without overlaps.
To make it possible for people to retain the old behavior, we
introduce the -qt-line-height-type property, which allows them
to override the default.
This also fixes output from toHtml() to use the new property
rather than set the minimum height of the paragraph or the
"line-spacing" property, which does not exist in either CSS nor
in Qt.
[ChangeLog][QtGui][Important Behavior Changes] When line height
is specified in pixels, this is now interpreted as the minimum
line height rather than an absolute line height to avoid overlaps.
To get the old behavior, use the -qt-line-height-type property in
CSS and set it to "fixed".

This fixes yet another bug where the selection spans both line
wraps and explicit line breaks. Offsetting the log clusters by
the text position in 342c909b340cb1bfbb95480fc79dcea21a470c83
was not entirely correct, because in some cases the script
item will refer to a specific part of the string, as indicated
by si.position, while iterator.itemStart is in the context
of the full string.
In this case, the log cluster array pointer we use refers to the
script item's part of the array, i.e. it is already offset by
si.position. Therefore, we must offset the logClusters pointer by the
text position *relative* to the current script item. Previously
we would actually offset by si.position twice in cases where
si.position != 0.
We want the text range to refer to the full string, though,
so it can be compared to other text ranges later. However,
in some cases when we are requesting only part of a script item,
then iterator.itemStart does not correspond to relativeFrom,
so in order for the text range search to work, we must pass in
the text positions we are using [relativeFrom, relativeTo],
though offset by si.position so that it refers to the full
string and not just the part addressed by the script item.

While extremely unlikely, there is a theoretical possibility that
the '0' glyph of a given font will have a width or height of 1 pixel,
in which case the (x + 1) / 2 way of getting the center would give us
an out of bounds pixel. We just default to true in this case, since
we cannot make any assumption based on the 0 glyph if it doesn't make
any sense. If the image is invalid, we default to false.

Scaled hinted glyphs looks ugly, see QTBUG-24846. It was fixed
in 6da6845f078e419ccb555fe1dd152e0ba82a7e88 by disabling hinting
for them. But at the same time that commit also disabled hinting
for glyphs with the most common transformation - rotating without
scaling.
Detect this type of transformation and don't disable hinting for it.

Both QFont::handle() and QFont::freetypeFace() used to
be available in Qt 4 but were removed in Qt 5. There's
currently no API to get access to the native font handle,
which the font engine holds in a way or another.
Similar to the way it was in Qt 4, the actual handle type
depends on the font engine currently in use. The types map
as follows:
Font Engine Native Handle
------------------------------------
DirectWrite IDWriteFontFace *
Freetype FT_Face
Mac CTFontRef
Win HFONT
All other font engines return a null handle.

Wrap the pairs of (void *ptr, void (*dtor)(void*)) in essentially
a std::unique_ptr. This simplifies code and provides the correct
implicit destruction, so we can drop the explicit glyph-cache
clear()ing in ~QFontEngine(), leaving that job to ~QLinkedList.
A subsequent change will turn the QLinkedList into a C array, the
clearing of which would otherwise cause excessive code bloat.
Since we can't use std::unique_ptr, yet, provide a hand-rolled
replacement for now, marking it for replacement with unique_ptr
once we can use it. Make that a local type instead of providing
a Qt-wide unique_ptr so we don't accidentally lock ourselves into
a half-baked std clone we can't get rid of anymore.
To prepare unique_ptr use with the same type-erased deleter
(function pointer) as now, replace a nullptr destroy_function
with a no-op function, so ~unique_ptr doesn't crash when we
port to it later.
Because QFreetypeFace contains the same construct and shares
payloads with QFontEngine, use the Holder there, too.
Even saves 150b in text size on optimized GCC 5.3 AMD64 builds.

The printf-style version of QDebug expands to a lot less code than the
std::ostream-style version. Of course, you pay in type safety (but
compilers warn about it these days), you cannot stream complex Qt
types and streaming QStrings is awkward, but in many cases you
actually improve on readability.
But the main reason is that something that's not supposed to be
executed under normal operation has no business bloating executable
code size.
This is not an attempt at converting all qWarnings() to printf-style,
only the low-hanging fruit.
In this first part, replace
qWarning() << "...";
with
qWarning("...");
In QTransform shared warning strings.

The enabler for finding selection ranges in Qt Quick had two bugs
which caused some selected text to disappear. Specifically, this
was the case for selected text where a line contained both an
explicit break and a break due to line wrapping.
First of all, the glyphsEnd that is passed into glyphRunsWithInfo()
is expected to be inclusive, since we are actually searching for
its index in the log cluster array. We would in certain cases
not find the glyph at all in the log clusters, thus the glyph
run would be set to overlap with any glyph run coming after it

Second of all, we need to start searching at the correct position
in the log clusters when searching for the correct rangeStart,
since rangeStart is initialized with textPosition. Otherwise, we
would in some cases never reach the start of the range, and
rangeStart would be set to textPosition + textLength, which is the
end of the range.

For writing systems where glyph substitutions are purely
cosmetic, we should disable them when letter spacing is set,
otherwise we get ligatures where the spacing is not applied.
To avoid changing Harfbuzz-NG upstream, we detect this
case when fetching the GSUB table and return an empty
blob instead.

This also reverts commit 018e670a26ff5a61b949100ae080f5e654e7bee8.
The change was introduced in 5.6. After the refactoring, 14960f52,
in 5.7 branch and a merge, it is not needed any more.

When getting the glyph runs from a QTextLayout with multiple
lines, the glyph runs would be merged if possible, but not their
bounding rects. This was an oversight.
[ChangeLog][Text][QTextLayout] QTextLayout::glyphRuns() now returns
united bounding rects for glyph runs that are merged.

For non-scalable fonts, the units_per_EM in FreeType is
documented to be undefined and will default to 0, which means
that any division by it will cause an exception.
The emSquareSize() function already checks if the font is scalable
and returns y_ppem if not, so lets use it instead in all locations
where we're not already sure the font is scalable.
[ChangeLog][Text][Freetype] Fixed a divide-by-zero exception
when accessing bitmap fonts.

QFlags::setFlag is most useful to replace explicit constructs like
if (condition) {
someFlags |= TheConditionFlag;
} else {
someFlags &= ~TheConditionFlag;
}
with
someFlags.setFlag(TheConditionFlag, condition);

The user-defined copy assignment and copy constructors
inhibit the move special member functions.
We cannot do something about it in Qt 5, because the
class is exported (which it shouldn't be), and because
making it trivially-copyable might change how it is
passed to functions by value, so we need to supply all
the missing member functions manually.
