Amir Masoud Abdol 7e074bd8a0 Use Qt CMake APIs to exclude files from Unity Build
This is a bit of a cleanup, mainly around unity build, and a few other
minor things:

- I replaced the direct inclusion of sources files using
  `set_source_files_properties`, and instead used
  `NO_UNITY_BUILD_SOURCES` when possible. In most cases, they are being
  excluded in their respective `qt_internal_extend_target` but sometimes
  I had to make a new extension.
- In few cases, we had to manually exclude the NO_PCH files, so, I
  instead passed them directly to the NO_PCH_SOURCES which also exclude
  them from the unity build as well.
- Removed a few unnecessary ""

Laszlo Agocs 7cf6c57648 Avoid incomplete textures in GL paint engine
...which can happen if the OpenGL implementation reuses IDs
so that a glGenTextures results in the same ID that was used
by a texture destroyed by glDeleteTextures just before.

In this case the lastTextureUsed tracking needs to be aware
and invalidate, otherwise the newly created texture is
assumed to be already existing (the ID is the same as before
after all), and so operations such as setting the minification
filter is skipped (which is fatal with OpenGL given that we
do not use mipmaps).

This is exercised in practice by the drawPixmapFragments test
introduced in the previous patch. On Intel graphics it would
work, but it does not render correctly with NVIDIA due to how
the driver's internal ID handling works.

Laszlo Agocs d6c5a2f917 GL paint engine: Fix drawPixmapFragments when using buffer objects
Until recently the buffer object-based code path (so not client-side
pointers) was only hit with a core profile context. This changed at
some point in 6.4 and later to support WebGL (that has no client-side
pointers, unlike OpenGL ES 2.0 it is based on). Now buffer objects
are preferred over client-side pointers, always. Problem is,
drawPixmapFragment() was never functional on this code path, it seems.

Expecting that transferMode() does all the uploadData() needed is wrong.
transferMode() bails out if the mode is the same as before, and that's
exactly what happens when an application calls drawPixmapFragments()
on the painter twice, after each other.

How exactly this works with client-side pointers is not fully clear, but
presumably the data buffer address stays the same so all pointers passed
in to the glVertexAttribPointer calls are valid, and it sources the data
for each draw call (probably), thus the rendering is all correct even
though only the first, not the second, drawPixmapFragment() led to
calling uploadData() internally.

Amends e487b07e18 although this patch on
its own is just as applicable pre-6.4 as well (to fix drawPixmapFragments
when using a core profile context).

Luca Di Sera e2fef733be Replace usages of Q_CLANG_QDOC with Q_QDOC
To allow the user to customize the C++ code that QDoc sees, so as to be
able to work-around some limitations on QDoc itself, QDoc defines two
symbols: Q_QDOC and Q_CLANG_QDOC, both of which are "true" during an
entire execution of QDoc.

At a certain point in time, QDoc allowed the user the choice between a
custom C++ parser and a Clang based one.

The Q_QDOC symbol would always be defined while the Q_CLANG_QDOC symbol
would be defined only when the Clang based parser was chosen.

In more recent times, QDoc always uses a Clang based parser, such that
both Q_CLANG_QDOC and Q_QDOC are always defined, making them equivalent.

To avoid using different symbols, and the possible confusion and
fragmentation that derives from it, all usages of Q_CLANG_QDOC are now
replaced by the equivalent usages of Q_QDOC.

Marc Mutz fc76767692 Long live Q_UNREACHABLE_RETURN()!
This is a combination of Q_UNREACHABLE() with a return statement.

ATM, the return statement is unconditionally included. If we notice
that some compilers warn about return after __builtin_unreachable(),
then we can map Q_UNREACHABLE_RETURN(...) to Q_UNREACHABLE() without
having to touch all the code that uses explicit Q_UNREACHABLE() +
return.

The fact that Boost has BOOST_UNREACHABLE_RETURN() indicates that
there are compilers that complain about a lack of return after
Q_UNREACHABLE (we know that MSVC, ICC, and GHS are among them), as
well as compilers that complained about a return being present
(Coverity). Take this opportunity to properly adapt to Coverity, by
leaving out the return statement on this compiler.

Apply the macro around the code base, using a clang-tidy transformer
rule:

    const std::string unr = "unr", val = "val", ret = "ret";
    auto makeUnreachableReturn = cat("Q_UNREACHABLE_RETURN(",
                                    ifBound(val, cat(node(val)), cat("")),
                                    ")");
    auto ignoringSwitchCases = [](auto stmt) {
        return anyOf(stmt, switchCase(subStmt(stmt)));
    };

    makeRule(
       stmt(ignoringSwitchCases(stmt(isExpandedFromMacro("Q_UNREACHABLE")).bind(unr)),
            nextStmt(returnStmt(optionally(hasReturnValue(expr().bind(val)))).bind(ret))),
       {changeTo(node(unr), cat(makeUnreachableReturn,
                                ";")),  // TODO: why is the ; lost w/o this?
        changeTo(node(ret), cat(""))},
       cat("use ", makeUnreachableReturn))
    );

where nextStmt() is copied from some upstream clang-tidy check's
private implementation and subStmt() is a private matcher that gives
access to SwitchCase's SubStmt.

A.k.a. qt-use-unreachable-return.

There were some false positives, suppressed them with NOLINTNEXTLINE.

They're not really false positiives, it's just that Clang sees the
world in one way and if conditonal compilation (#if) differs for other
compilers, Clang doesn't know better. This is an artifact of matching
two consecutive statements.

I haven't figured out how to remove the empty line left by the
deletion of the return statement, if it, indeed, was on a separate
line, so post-processed the patch to remove all the lines matching
^\+ *$ from the diff:

  git commit -am meep
  git reset --hard HEAD^
  git diff HEAD..HEAD@{1} | sed '/^\+ *$/d' | recountdiff - | patch -p1

We've been requiring C++17 since Qt 6.0, and our qAsConst use finally
starts to bother us (QTBUG-99313), so time to port away from it

Since qAsConst has exactly the same semantics as std::as_const (down
to rvalue treatment, constexpr'ness and noexcept'ness), there's really
nothing more to it than a global search-and-replace, with manual

Laszlo Agocs 72dd23cf53 Defer creating the special shaders in the texture blitter
Port of the 5.15 change. It is not strictly required for Qt 6 since the
immediate problem of failing to compile some of the shaders with some
drivers will pop up much more rarely in practice, because neither
Multimedia nor the backing store compositor for
QOpenGLWidget/QQuickWidget use QOpenGLTextureBlitter in 6.4 and newer.

To maintain the internal behavior between 5 and 6, the patch is
nonetheless ported to Qt 6. It also has a performance benefit for
the users of the blitter, because now the special shader variants
(for rectangle or external textures) are only created when needed.

Marc Mutz 04ab0905e3 Gui: mark types Q_PRIMITIVE_TYPE when they're held in QDataBuffer
QDataBuffer assumes that its template argument is a POD, iow: it's ok
to not run ctors and dtors and assign a value into uninitialized
memory.

In Qt, we call that Q_PRIMITIVE_TYPE. Asserting that the QDataBuffer
value_type is not QTypeInfo::isComplex, however, has shown that a
large number of types had not been marked as such, sometimes for good
reason, e.g. because their default constructor doesn't
value-initialize all members, but sets some of them to -1.

Since QDataBuffer doesn't memset the memory to zero, it doesn't
matter, as the code obviously has to have worked before, with
uninitialized memory, and all-zeros is just a special, if common, form
of uninitialized memory.

I also tried to assert is_pod in QDataBuffer (working around the fact
that that particular trait is deprecated), but found that almost none
of the types in question were, in fact, trivial. We should fix this,
because it means the compiler is generating code that's less efficient
than it could be, but that's for another patch.

All types marked as Q_PRIMITIVE_TYPE in this patch are private API, so
this doesn't affect users.

For PathSimplifier::Event, had to shorten the unnamed namespace to not
include the member functions, because Q_DECLARE_TYPEINFO cannot appear
in a namespace other than the Qt one.

Morten Sørvig d38118c808 Make rhiFlush() support custom source DPR
The rhiFlush() implementation currently assumes that
QWindow->devicePixelRatio() is the correct scale factor for
transforming device independent window geometry to source geometry.

However, this assumption does not hold if/when we add support
for drawing to a rounded-up DPR, with a downscale later in
the rhiFlush implementation.

Fix this by adding a sourceDevicePixelRatio argument to rhiFlush(),
which is set to either QWindow::devicePixelRatio() or
QWidget::devicePixelRatio(), depending on from where it is used.

Change deviceRect() and friends in qbackingstoredefualtcompositor.cpp
to be scale*() functions instead which take a scale factor instead
of a QWindow. Update call sites to use srouceDevicePixelRatio
where that makes sense.

Eirik Aavitsland f67d89ebde Support cosmetic brush patterns in the pdf and opengl paint engines
This implements the recent functionality extension of painting
cosmetic (untransformed) brush patterns, and the corresponding
NonCosmeticBrushPatterns render hint, in the pdf and opengl paint
engines.

As part of the implementation it also fixes a couple of pre-existing
bugs in the opengl engine, relating to updating the brush after
changes in transformation or brush origin.

As a driveby, it also includes a minor fix for the lance testing tool:
request stencil buffer, as that is needed and not always provided by
default. This echoes a recent fix done to tst_baseline_painting.

A number of consequences of the new rhi-based backingstore
composition were not handled. Most importantly, the fact
that RasterGLSurface is not a thing anymore in practice
causes challenges because we can no longer decide just
based on the surfaceType what a QWindow with OpenGLSurface
would be. (a plain GL window or a GL window with a backing
store?) Also, the backingstore needs to be able to initialize
its backing QRhi by itself, because with eglfs going through
OpenGL is the only way.

Laszlo Agocs 68a4c5da9a Compose render-to-texture widgets through QRhi
QPlatformTextureList holds a QRhiTexture instead of GLuint. A
QPlatformBackingStore now optionally can own a QRhi and a
QRhiSwapChain for the associated window.  Non-GL rendering must use
this QRhi everywhere, whereas GL (QOpenGLWidget) can choose to still
rely on resource sharing between contexts. A widget tells that it
wants QRhi and the desired configuration in a new virtual function in
QWidgetPrivate returning a QPlatformBackingStoreRhiConfig. This is
evaluated (among a top-level's all children) upon create() before
creating the repaint manager and the QWidgetWindow.

In QOpenGLWidget what do request is obvious: it will request an
OpenGL-based QRhi. QQuickWidget (or a potential future QRhiWidget)
will be more interesting: it needs to honor the standard Qt Quick
env.vars. and QQuickWindow APIs (or, in whatever way the user
configured the QRhiWidget), and so will set up the config struct
accordingly.

In addition, the rhiconfig and surface type is (re)evaluated when
(re)parenting a widget to a new tlw. If needed, this will now trigger
a destroy - create on the tlw. This should be be safe to do in
setParent. When multiple child widgets report an enabled rhiconfig,
the first one (the first child encountered) wins. So e.g. attempting
to have a QOpenGLWidget and a Vulkan-based QQuickWidget in the same
top-level window will fail one of the widgets (it likely won't
render).

RasterGLSurface is no longer used by widgets. Rather, the appropriate
surface type is chosen.

The rhi support in the backingstore is usable without widgets as well.
To make rhiFlush() functional, one needs to call setRhiConfig() after
creating the QBackingStore. (like QWidget does to top-level windows)

Most of the QT_NO_OPENGL ifdefs are eliminated all over the place.
Everything with QRhi is unconditional code at compile time, except the
actual initialization.

Having to plumb the widget tlw's shareContext (or, now, the QRhi)
through QWindowPrivate is no longer needed.  The old approach does not
scale: to implement composeAndFlush (now rhiFlush) we need more than
just a QRhi object, and this way we no longer pollute everything
starting from the widget level (QWidget's topextra -> QWidgetWindow ->
QWindowPrivate) just to send data around.

The BackingStoreOpenGLSupport interface and the QtGui - QtOpenGL split
is all gone. Instead, there is a QBackingStoreDefaultCompositor in
QtGui which is what the default implementations of composeAndFlush and
toTexture call. (overriding composeAndFlush and co. f.ex. in eglfs
should continue working mostly as-is, apart from adapting to the
texture list changes and getting the native OpenGL texture id out of
the QRhiTexture)

As QQuickWidget is way too complicated to just port as-is, an rhi
manual test (rhiwidget) is introduced as a first step, in ordewr to
exercise a simple, custom render-to-texture widget that does something
using a (not necessarily OpenGL-backed) QRhi and acts as fully
functional QWidget (modeled after QOpenGLWidget). This can also form
the foundation of a potential future QRhiWidget.

It is also possible to force the QRhi-based flushing always,
regardless of the presence of render-to-texture widgets. To exercise
this, set the env.var. QT_WIDGETS_RHI=1. This picks a
platform-specific default, and can be overridden with
QT_WIDGETS_RHI_BACKEND. (in sync with Qt Quick) This can eventually be
extended to query the platform plugin as well to check if the platform
plugin prefers to always do flushes with a 3D API.

QOpenGLWidget should work like before from the user's perspective, while
internally it has to do some things differently to play nice and prevent
regressions with the new rendering architecture. To exercise this
better, the qopenglwidget example gets a new tab-based view (that could
perhaps replace the example's main window later on?). The openglwidget
manual test is made compatible with Qt 6, and gets a counterpart in form
of the dockedopenglwidget manual test, which is a modified version of
the cube example that features dock widgets. This is relevant in
particular because render-to-texture widgets within a QDockWidget has
its own specific quirks, with logic taking this into account, hence
testing is essential.

For existing applications there are two important consequences with
this patch in place:

- Once the rhi-based composition is enabled, it stays active for the
lifetime of the top-level window.

- Dynamically creating and parenting the first render-to-texture
widget to an already created tlw will destroy and recreate the tlw
(and the underlying window). The visible effects of this depend on the
platform.  (e.g. the window may disappear and reappear on some,
whereas with other windowing systems it is not noticeable at all -
this is not really different from similar situtions with reparenting
or when moving windows between screens, so should be acceptable in
practice)

- On iOS raster windows are flushed with Metal (and rhi) from now on
(previously this was through OpenGL by making flush() call
composeAndFlush().

Eirik Aavitsland 423b650938 Fix painting clipping glitches with fractional scaling
In QPainter, clipping can only be done on whole pixels. The various
ways of specifying a clipping rectangle to the QPainter API have been
inconsistent in how fractional rectangles (either specified directly,
or as a result of fractional scaling) are mapped (rounded) to integer
coordinates.

Also, the mappings have not made sure to keep the edge-to-edge
property of clip rects under scaling. This is particularly important
when scaling QRegions with multiple rects, as QRegion is designed on
the assumption that an area can be described as a set of edge-to-edge
rects.

The fix rounds a clip rect identically with a fill rect. (Indeed, a
followup plan would be to merge QRasterPaintEngine's
toNormalizedFillRect() with the rectangle rounding function in this
commit).

Notably, a QRectF clip is now interpreted the same as a QPainterPath
clip describing the same area.

This modifies d9cc149995
