This was added by 9ff76c27b9 on
the basis that it signifies a shaping error and would later assert
or crash.
But the line is easily reachable by user code. If Harfbuzz returns
0 glyphs, it just means it is unable to shape the string, for instance
if the input string only contains default ignorables (like a ZWJ)
and does not have any appropriate glyph to use for replacement.
Qt expects there to always be at least one glyph in the output
(num_glyphs == 0 is used to indicate shaping is not yet done), so
to avoid asserts later on, we simply populate the output with a
single 0 token, which is a required entry in the font that is
reserved for representing unrepresentable characters.
This also adds a test and therefore a zero-width joiner to the test
font to reproduce the issue.

expected to be an issue, so this workaround and therefore the Carbon

On Windows, the wrong value was used to calculate the
design-to-device scale. The assumption has been that tmHeight
in the TEXTMETRIC is the pixel size of the em square, but
it is not, it's the height of the font (ascent + descent).
The pixel size of the font is defined to be the em square size
in pixels.
On OS X, the kerning data was never actually read from the
font. I've added a lazy initialization for this similar to
the one in the FT engine.
This was discovered when investigating QTBUG-48546, as it turned
out that the kerning information extracted by Qt in this case was
different from the one used by Harfbuzz.
I've changed testfont.ttf to kern "_2" so that the digit is positioned
directly on top of the underscore and constructed a test.

The main reasons for doing this are:
1. _qpa.h end up in the master QtGui include file. QtGui is meant for
userland applications. qpa code is neither binary nor source compatible.
Inadvertant use of QPA api makes the user code binary-incompatible.
2. syncqt creates forwarding headers for non-private header files. This
gives people the impression that this is public API.
As discussed on the mailing list, even though QPA api is internal and subject
to change, it needs to treated differently from private headers since they
will be used by in-qtbase and out-of-qtbase plugins.
This commit does the following:
1. The _qpa in QPA header files is dropped.
2. syncqt now treats any file with qplatform prefix as a special file and
moves it to qpa/ directory. The recommended way of using QPA API in plugins
is: #include <qpa/qplatformfoo.h>. This allows the user include QPA API
from multiple modules (for example, qplatformfoo might be in QtPrintSupport)
3. The user needs to explicitly add QT += <module>-private to get access to
the qpa api.
4. Creates compat headers for the olden style qplatformfoo_qpa.h and QPlatformFoo
includes.
This commit does not change the cpp filenames. This requires a more careful
merging of existing non qpa cpp files and existing cpp files on a case by
case basis. This can be done at anytime.
The following files are not renamed as part of this changed but will be fixed
as part of a future change:
src/gui/kernel/qgenericpluginfactory_qpa.h
src/gui/kernel/qgenericplugin_qpa.h
src/gui/kernel/qwindowsysteminterface_qpa.h
files were renamed using
for x in `find . -name "qplatform*_qpa.h"`; do git mv $x "${x/_qpa.h/.h}"; done
for x in `find . -name "qplatform*_qpa_p.h"`; do git mv $x "${x/_qpa_p.h/_p.h}"; done
includes were renamed using script
