0efe79f80d Rename the new platform APIs from QPlatformInterface to QNativeInterface
We were already using the 'native' nomenclature when referring to these
kinds of APIs, e.g. when talking about native handles, or the existing
QPlatformNativeInterface on a QPA level. Using 'native' for the user
facing APIs also distinguishes them from the 'platform' backend layer
in QPA and elsewhere.

f51e6552e3 End touch->mouse synthesis when the chosen touchpoint is released
During delivery of a TouchBegin event, if no widget accepts it,
we begin treating the first touchpoint as a synth-mouse, as before.
If a second touchpoint is pressed or released in any order, it's
irrelevant: the fake mouse button is released as soon as the first
touchpoint is released.  This fixes the bug that such a scenario
caused the mouse release not to be sent, so that a widget could get
"stuck" in pressed state.

0b7aef08dc rhi: vk: Alter command buffer strategy
Reports on the Web have it that there's nothing guaranteeing a
driver does any actual freeing of resources then doing
vkFreeCommandBuffer for a command buffer from a command pool that
does not have VK_COMMAND_POOL_CREATE_RESET_COMMAND_BUFFER_BIT, thus
leading to continuously growing resource usage with our current
allocate/free pattern. It could be that this is the source of out
of memory problems we are seeing on some Android devices.

Instead of just going straight for said command pool flag and doing
ResetCommandBuffer for the command buffers individually, take one
step further and use per-slot (slot being 0 or 1 if QVK_FRAMES_IN_FLIGHT
is 2) command pools. The current pool is reset in each
beginFrame/beginOffscreenFrame, moving all allocated command buffers
to the initial state (while other command buffers with the other pool
are not affected).

This may be (while impossible to tell from just guessing based on the
spec) our best approach to command buffer allocation since a Vulkan
implementation can likely just use some simple per pool allocator,
knowing that we never want to free or reset individual command buffers,
but we rather only reset the whole pool at once.

The option of importing an existing VkCommandPool when creating the
QRhi instance is now gone, but there was probably no point in offering
that in the first place.

When it comes to VK_COMMAND_POOL_RESET_RELEASE_RESOURCES_BIT it will
not be set unless releaseCachedResources() (in Qt Quick this is hooked
into QQuickWindow::releaseResources()) was called. What this does in
practice is unknown, but have an option to set it now and then if the
application really wants.

While we are at it, rename secondaryCbs to activeSecondaryCbStack to
indicate what it really is. (it's a stack as each call to
beginExternal() pushes a new one, while each endExternal() pops)

d92b0e18c1 rhi: Make per-frame flags per-pass where appropriate
ExternalContentsInPass becomes a per-pass flag now. Why is this
beneficial? Because while Qt Quick has no choice for its render
pass, not being able to guess if the application wants to do some
native rendering in there, Quick 3D's render passes, all the ones
that are under Quick3D's control, do not have native rendering
from the application in them, and so using secondary command
buffers with Vulkan is not necessary.

Introduce something similar for compute and OpenGL. By knowing that
none of the resources used in a pass are used with a compute pass
(e.g. because we know that there are no compute passes at all) a small
amount of time can be saved by skipping tracking buffers and textures
because the only purpose of said tracking is to generate barriers that
are relevant only to compute.

It also demonstrated that the tests were out of sync with reality:
since a97759a336c597327cb82eebc9f45c793aec32c9 QMouseEvent::button()
and QWindowSystemInterfacePrivate::MouseEvent::button should be the
button that changes state of course; but when a button is pressed,
we are reacting to it after the fact, so QMouseEvent::buttons() and
QWindowSystemInterfacePrivate::MouseEvent::buttons should include the
new button that was just pressed.  Likewise when a button was released,
we send the event with buttons _omitting_ the button that was just
released.

2692237bb1 Track grab state in QPointingDevicePrivate::activePoints
QQuickEventPoint instances were very long-lived and got reused from one
event to the next.  That was initially done because they were "heavy"
QObjects; but it also became useful to store state in them between
events. But this is in conflict with the ubiquitous event replay
code that assumes it's OK to hold an event instance (especially
a QMouseEvent) for any length of time, and then send it to some widget,
item or window. Clearly QEventPoints must be stored in the QPointerEvent,
if we are to avoid the need for workarounds to keep such old code working.
And now they have d-pointers, so copying is cheap. But replay code
will need to detach() their QEventPoints now.

QEventPoint is useful as an object to hold state, but we now store
the truly persistent state separately in an EventPointData struct,
in QPointingDevicePrivate::activePoints. Incoming events merely
update the persistent points, then we deliver those instead.
Thus when event handler code modifies state, it will be remembered
even when the delivery is done and the QPA event is destroyed.

This gets us a step closer to supporting multiple simultaneous mice.

Within pointer events, the points are moved up to QPointerEvent itself:
 QList<QEventPoint> m_points;
This means pointCount(), point(int i) and points() can be non-virtual.
However in any QSinglePointEvent, the list only contains one point.
We hope that pessimization is worthwhile for the sake of removing
virtual functions, simplifying code in event classes themselves, and
enabling the use of the range-for loop over points() with any kind of
QPointerEvent, not just QTouchEvent. points() is a nicer API for the
sake of range-for looping; but point() is more suited to being
non-const.

In QML it's expected to be OK to emit a signal with a QPointerEvent
by value: that will involve copying the event.  But QEventPoint
instances are explicitly shared, so calling setAccepted() modifies
the instance in activePoints (EventPointData.eventPoint.d->accept);
and the grabbers are stored separately and thus preserved between events.
In code such as MouseArea { onPressed: mouse.accepted = false }
we can either continue to emit the QQuickMouseEvent wrapper
or perhaps QEvent::setAccepted() could become virtual and set
the eventpoint's accepted flag instead, so that it will survive
after the event copy that QML sees is discarded.

The grabChanged() signal is useful to keep QQuickWindow informed
when items or handlers change exclusive or passive grabbers.

When a release happens at a different location than the last move event,
Qt synthesizes an additional move.  But it would be "boring" if
QEventPoint::lastXPosition() accessors in any released eventpoint always
returned the same as the current QEventPoint::xPosition()s just because
of that; and it would mean that the velocity() must always be zero on
release, which would make it hard to use the final velocity to drive an
animation.  So now we expect the lastPositions to be different than
current positions in a released eventpoint.

De-inline some functions whose implementations might be subject to
change later on.  Improve documentation.

Since we have an accessor for pressTimestamp(), we might as well add one for
timestamp() too.  That way users get enough information to calculate
instantaneous velocity, since the plan is for velocity() to be somewhat
smoothed.

25351dcc54 Long live QKeyCombination!
C++20 via P1120 is deprecating arithmetic operations between
unrelated enumeration types, and GCC 10 is already complaining.
Hence, these operations might become illegal in C++23 or C++26 at
the latest.

A case of this that affects Qt is in key combinations: a
QKeySequence can be constructed by summing / ORing modifiers and a
key, for instance:

  Qt::CTRL + Qt::Key_A
  Qt::SHIFT | Qt::CTRL | Qt::Key_G (recommended, see below)

The problem is that the modifiers and the key belong to different
enumerations (and there's 2 enumerations for the modifier, and one
for the key).

To solve this: add a dedicated class to represent a combination of
keys, and operators between those enumerations to build instances
of this class.

I would've simply defined operator|, but again docs and pre-existing
code use operator+ as well, so added both to at least tackle simple
cases (modifier + key).

Multiple modifiers create a problem: operator+ between them yields
int, not the corresponding flags type (because operator+ is not
overloaded for this use case):

  Qt::CTRL + Qt::SHIFT + Qt::Key_A
  \__________________/      /
          int              /
           \______________/
                  int

Not only this loses track of the datatypes involved, but it would
also then "add" the key (with NO warnings, now its int + enum, so
it's not mixing enums!) and yielding int again.

I don't want to special-case this; the point of the class is
that int is the wrong datatype. Everything works just fine when
using operator| instead:

  Qt::CTRL | Qt::SHIFT | Qt::Key_A
  \__________________/      /
      Qt::Modifiers        /
           \______________/
            QKeyCombination

So I'm defining operator+ so that the simple cases still work,
but also deprecating it.

Port some code around Qt to the new class. In certain cases,
it's a huge win for clarity. In some others, I've just added
the necessary casts to make it still compile without warnings,
without attempting refactorings.

[ChangeLog][QtCore][QKeyCombination] New class to represent
a combination of a key and zero or more modifiers, to be used
when defining shortcuts or similar.

[ChangeLog][Potentially Source-Incompatible Changes] A keyboard
modifier (such as Qt::CTRL, Qt::AltModifier, etc.) should be
combined with a key (such as Qt::Key_A, Qt::Key_F1, etc.) by using
operator|, not operator+.  The result is now an object of type
QKeyCombination, that stores the key and the modifiers.

319462559f Port tst_qiconhighdpi to the new QIcon::pixmap() API
Port the high-dpi icon test to use the new pixmap()
API which takes the target devicePixelRatio as an argument.

This means we can run the fromTheme test at dpr = {1,2,3},
instead of at the current global devicePixelRatio only.

756d7facf6 Fix tst_QHighDpiScaling::scale
Without an override for logicalDpi() the base class implementation
would use the geometry of the screen to figure out the DPI, and end
up with ~100, which combined with a 96DPI base logical DPI would
give a wrong scale factor.

b5f972361a Introduce QWindow::paintEvent with QPA plumbing
The explicit paint event on QtGui and QPA level allows us to untangle
the expose event, which today has at least 3 different meanings.

It also allows us to follow the platform more closely in its semantics
of when painting can happen. On some platforms a paint can come in
before a window is exposed, e.g. to prepare the first frame. On others
a paint can come in after a window has been de-exposed, to save a
snapshot of the window for use in an application switcher or similar.

The expose keeps its semantics of being a barrier signaling that the
application can now render at will, for example in a threaded render
loop.

There are two compatibility code paths in this patch:

  1. For platform plugins that do not yet report the PaintEvents
     capability, QtGui will synthesize paint events on the platform's
     behalf, based on the existing expose events coming from the platform.

  2. For applications that do not yet implement paintEvent, QtGui will
     send expose events instead, ensuring the same behavior as before.

For now none of the platform plugins deliver paint events natively,
so the first compatibility code path is always active.

acbf9a858b Cleanup QTypeInfo
Remove QTypeInfo::isStatic, as that's not used anymore in Qt 6.
Also remove sizeOf, it's unused, and we have QMetaType for that if
required.
Remove all typeinfo declaractions for trivial types, as the default
template covers them correctly nowadays.

Finally set up a better default for isPointer, and do some smaller
cleanups all over the place.

b77a3f47c9 Rename confusingly named QFont/QPalette::resolve overloads
Having three methods with the same name doing different things is
unnecessarily confusing, so follow the standard naming convention in
Qt and call the getter of the resolve mask resolveMask, and the setter
setResolveMask. These methods were all documented as internal.

The publicly documented resolve() method that merges two fonts and
palettes based on the respective masks remains as it is, even though
'merge' would perhaps be a better name.
