d76be5530a Use correct test to add C++14 to the project configuration
Only add C++14 to the project configuration when C++14 support is
available on the platform.  Adding it because the platform supports
C++11 doesn't work when the platform _only_ supports C++11 (e.g.,
QNX 6.6.0).

50cd0daf29 Fix kerned advances in QRawFont on OS X and Windows
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.

[ChangeLog][QRawFont] Fixed kerning on advances in QRawFont for
OS X and Windows.

1005b7a0de Long live qUtf16Printable()
QString::asprintf() has the ability to take a ushort* array as
obtained from QString::utf16() and insert that into the output
with an %ls conversion.

But no-one ever used this, because just passing QString::utf16()
to QString::asprintf() creates a warning about wchar_t* expected,
but ushort* provided.

The new qUtf16Printable() macro adds the necessary casts (via void*
to prevent any "type-punned pointer" warnings) to make
passing QString::utf16() to QString::asprintf() work silently.

This should greatly reduce the need to do a round-trip via utf-8
just to print the contents of a QString.

[ChangeLog][QtCore] Added qUtf16Printable().

00a855d643 Avoid having division caught up in parsing of comments.
A loop to skip space and comments was meant to break on anything else
but would have not broken on a division operator (where it should) due
to it getting caught in the check for a comment-start, without falling
back suitably when it didn't complete that check.

Managed to contrive a suitably twisted change to findDeps test to
reveal the bug; broken previously, now fixed.  Not ideal, as it relied
on another bug to fail previously - backslash-newline shouldn't end a
preprocessing directive line - but it should still pass once that's
fixed, too.  Exercising a bug in qmake usually involves code that
won't compile anyway, making it tricky to write a test that reveals
the bug but that passes once it's fixed.

ceb71d5b3f tst_QString: add checks for sprintf's %ls
... at the cost of a bunch of warnings about
ushort*/wchar_t*.

It wasn't checked at all, which isn't really a solution,
either.

Split off the %s checks into a separate function, which
makes obvious the sorry state of sprintf non-%s, non-%d
testing that's left.

5ff7a3d96e Add {add,sub,mul}_overflow for signed integers.
In C++, signed overflow math is Undefined Behavior. However, many CPUs
do implement some way to check for overflow. Some compilers expose
intrinsics to use this functionality. If the no intrinsic is exposed,
overflow checking can be done by widening the result type and "manually"
checking for overflow. Or, for X86, by using inline assembly to use the
CPU features.

Used in QtQml.

7c6625b105 Support mixing native child widgets with texture-based ones
Currently QOpenGLWidget and QQuickWidget do not support having native
child widgets inside the same top-level window. In some cases this is
inevitable, f.ex. multimedia may require native windows when used from
widget apps. winId() calls made for various (valid or invalid) reasons
are also problematic.

There are no blockers for supporting this setup, however. By storing
multiple texture lists (one for each subtree where the root is a
native widget), adding the missing markDirtyOnScreen calls, letting
each native widget access the correct texture list (i.e. the one
corresponding to its children) when they are (separately) flushed, and
fixing composeAndFlush() to take the update region and the (native
child) offset into account, it can all be made functional.

The change also fixes the issue of keeping GL-based compositing
enabled even after all render-to-texture widgets in the window become
hidden. Due to the changes of how such widgets are gathered,
composeAndFlush() is not invoked anymore when no such widgets are
discovered for a given native parent. This is great since having
compositing enabled infinitely is an issue for applications like Qt
Creator that implement certain views with QQuickWidgets but cannot
afford the cost of texture uploads in other places (e.g. for the text
editor) on slower machines.

The openglwidget manual test is greatly enhanced to test various
situations (MDI, scroll areas, tab widgets, QOpenGLWidget as native
child, QOpenGLWidget with non-tlw native parent, etc.)
