c02ca6752a Fix handling of invalid modifiers in QKeySequence.
When decoding a string don't assume valid modifier strings. If a
modifier string is unknown return Qt::Key_unknown instead of skipping
the modifier.
Currently 'Win+a' is decoded to 'A' but should be Qt::Key_unknown.

85a77cd5c8 Retire QTest::pixmapsAreEqual().
QTest::pixmapsAreEqual() was left in the Qt4 API for compatibility with
some old tests written for Qt3.  QCOMPARE() is the preferred way to
compare QPixmaps and provides superior diagnostic output when a
comparison fails.

This commit removes QTest::pixmapsAreEqual() from the testlib API and
replaces the last few remaining calls with QCOMPARE.

3064c1bc8c Remove redundant touch processing in QtGui and widgets.
The duplicated hash tables in QGuiApplicationPrivate and
QApplicationPrivate are now unified into one single hash table in
QGuiApplicationPrivate. This also reduced the number of lookups.

The extra processing needed to keep the touch points' first/lastPos
values in sync is now done only once, in QGuiApplication. This
eliminates the performance penalty (for widget-based apps) that was
introduced during the QPA migration.

As an added bonus the patch adds support for touch events arriving
simultaenously from multiple devices. This was broken before: As there
is no guarantee that two devices/drivers will not send touch points
with the same ID, using structures with only the ID as key is
wrong. The proper key is composed of the device ID (that is, a
QTouchDevice pointer) and the touch point ID.

The exported internal function qt_translateRawTouchEvent() has been
removed. This function cannot work properly in the QPA world: It
injected touches into the widget subsystem (QApplication) only which
is wrong, and would result in half-filled touch events due to not
routing the injected data through QGuiApplication. Autotests using
this function are migrated to
QWindowSystemInterface::handleTouchEvent().

0786716ce5 Fix failing unit tests.
The test that was failing was the readFromDevice one - where the
extension is not known.

Looks as though image detection is required in a positive way, that is
it is not enough to say I think I can read this file, and then fail if
the format is "corrupt", you must be certain that the file was intended
to be that format.

In the case of TGA the original format has no magic byte header, and no
consistent way to check if it really is a TGA file.  With 2.0 the footer
was added at the end, so that can be checked for confirming the file is
TGA.  However rejecting files which do not have this means that old TGA
files will not be read.

On a quick survey TGA files that have been used in applications so far
all seem to be 2.0 TrueVision, so for now, lets just reject earlier
files and see how it goes.

Also add reading the tga test file to the readFromDevice test.

91b48208f5 Add touchEvent() virtual to QWindow.
Unlike keyPressEvent(), mousePressEvent(), etc. the touch events had
no equivalent so one had to fall back to reimplementing event() or
using an event filter. This is now corrected by introducing
touchEvent(). Touch events are finally becoming a first-class citizen
in Qt 5.

4222603f8e Extend touch events.
The capability flags indicate which information is valid in the touch
points. Previously there was no way to tell if e.g. the value returned
by pressure() is actually the value provided by the driver/device or
it is just something bogus due to pressure not being supported.

The points' flags return information about the individual touch
points. One use case is to differentiate between touches made by
finger and pen.

Velocity, if available, is now also exposed.

Each touch point can now contain an additional list of "raw"
positions. These points are not reported individually but are taken
into account in some way by the underlying device and drivers to
generate the final, "accurate" touch point. In case the underlying
drivers expose these additional positions, they are made available in
the lists returned by the touch points' rawScreenPosition().

The raw positions are only available in screen coordinates to prevent
wasting time with mapping from global positions in applications that
do not use this data. Instead, apps can query the QWindow to which the
touch event was sent via QTouchEvent::window() and can call
mapFromGlobal() manually if they need local raw positions.

The capability and device type information is now held in a new
QTouchDevice class. Each touch event will contain only a pointer to
one of the global QTouchDevice instances. On top of type and
capability, the new class also contains a name which can be used to
differentiate between multiple touch input devices (i.e. to tell from
which one a given QTouchEvent originates from).

The introduction of QTouchDevice has three implications: The
QTouchEvent constructor and QWindowSystemInterface::handleTouchEvent
need to be changed (to pass a QTouchDevice pointer instead of merely a
device type value), and each platform or generic plug-in is now
responsible for registering one or more devices using the new API
QWindowSystemInterface::registerTouchDevice.

202127f860 Ensure that QOpenGLMultiGroupSharedResources are cleaned up
When a GL context group is destroyed, all multi-group shared
resources associated with the group should be cleaned up.
Otherwise we could get a double deletion in the resource's

deleted group.

The missing cleanup resulted in a crash when the global
static qt_gl_functions_resource was destroyed, first seen
in the tst_examples autotest in qtdeclarative. It possibly
didn't manifest before because it's event loop-dependent
(the contexts are deleted via deleteLater()).

c0fb09465b gui: eliminated usage of qttest_p4.prf
qttest_p4.prf was added as a convenience for Qt's own autotests in Qt4.
It enables various crufty undocumented magic, of dubious value.
Stop using it, and explicitly enable the things from it which we want.

27f9f136f7 Remove SkipMode parameter from QSKIP calls.
The previous commit removed SkipMode from the testlib APi.  This commit
removes the parameter from all calls to QSKIP.

9e92ecde74 Provide API for "placement new" construction of meta-types
By making it possible to specify the place in memory where a
type should be constructed, any meta-type can be allocated on
the stack, for example. In the QML/JS QObject binding, this
makes it possible to call slots and access properties from
JavaScript without having to perform any mallocs (e.g. due to
QVariant creation) in the C++ <--> JS value conversion, in
the best case.

In addition to QMetaType::construct() and QMetaType::destruct(),
this change introduces QMetaType::typeSize(), which returns the
size of a type in bytes. This can be used to prepare a suitable
buffer for constructing a type using construct().

Benchmarks indicate that in-place construction is 2-5x faster
than normal construction for core and GUI types on linux-g++.

Note that there is already a QMetaType::construct() function
in Qt 4, which has been renamed to QMetaType::create() in Qt 5.
In order to avoid existing usages of construct() in user code
to call the Qt 5 construct() (when they really meant to call
create()), the third argument ("copy") of construct() is made
mandatory. Hence, calls to QMetaType::construct() written for
Qt 4 will cause a compile error when compiled with Qt 5, and
the user must adapt his code.

The DEPENDS_ON macro didn't do anything and has misled many users to
think that they can write test functions that depend on other test
functions.
