Quoting a blog from 2009, "this class is responsible for figuring out which parts
of the window surface needs to be updated prior to showing it to screen, so it's
really a repaint manager."
https://blog.qt.io/blog/2009/12/16/qt-graphics-and-performance-an-overview/
What better time to do the rename than 10 years later!

It was added for Symbian almost 10 years ago (d7057e7c1f1a), for a somewhat
dubious use-case. The Symbian code is since long gone (ae30d7141), so the
remaining pieces are just adding complexity to the already intricate workings
of the QtWidgets backingstore/painting logic.

The QVector dirtyOnScreenWidgets was aggregated by pointer, which
makes no sense, as a QVector is just as large as a pointer (and even
in Qt 6, when it will be larger, it's not going to be horrible). But
this complicated the code quite a bit.
Aggregate by value instead (it's just one of three such vectors now).
Drive-by fixes:
- use QVector::removeAll() instead of rolling your own
- port two indexed loops to ranged ones. In the first case, it's safe,
as the loop body clearly doesn't touch the iteratee (it's just a
std::accumulate). In the second, the question no longer applies, as
we're now using a consume loop.

QWidget does not handle QWindow and QPlatformWindow being destroyed
behind its back, and the QWidget state for internalWinId and the
Qt::WA_WState_Created attribute can easily get out of sync with
reality.
To avoid QWidgetBackingStore mistakenly thinking that a widget does
not have a platform window it can operate on we use the QWindow and
QPlatformWindow handles directly, instead of relying on the winId.
This is a stop gap until we can teach QWidget to deal with dynamic
changes to its underlying window handles.

Opt out of switching between the normal and OpenGL based flush paths.
Once a QOpenGLWidget or QQuickWidget becomes visible in a window, the
window contents will be composed using OpenGL from that point on, even
if said widgets become invisible afterwards. Now that Qt Creator does
not rely on QQuickWidget the issue is less burning anyways.

The textureChildSeen flag is set on each widget the first time it has
a child needing textures, which triggers the composeAndFlush codepath.
If a top level widget had a child needing this codepath, but other
native children not needing it, we ended up always using composeAndFlush
for the native children, since we were checking textureChildSeen of the
top level widget.
We should check the child widget instead, which will never have the flag
set unless itself had children that required composeAndFlush. This matches
the logic in findAllTextureWidgetsRecursively, which also checks the
child widget and not the top level widget.

Get region of overlapped widgets and scroll only non-overlapped parts
of image. Next, schedule an update for overlapped widgets region.
This patch improves scrolling performance when scrolled widget has
overlapped widgets.
Common use cases:
- faster scrolling when using "StyleHint::SH_ScrollBar_Transient",
- faster scrolling of zoomed image with semi-transparent thumbnail.
Accelerated scrolling with overlapped widgets is not available when
scale factor is non-integer.

The resources allocated by QPlatformBackingStore are owned by the class,
and should be allocated in a context the class also owns. This removes
the asymmetry of having to pass in a context to composeAndFlush, while
having to make the same context current before destroying the platform
backingstore.
The context owned by QPlatformBackingStore is shared with the associated
window though a new QWindowPrivate::shareContext() API.
The result is that on e.g. iOS, the backingstore does not need to tie
the resource allocation of QPlatformBackingStore to the global share
context, but can instead tie them to the per-window context, and hence
clean them up after each window is closed.

Commit c5db8fc74 changed all instances of Q_WS_FOO to have the prefix
Q_DEAD_CODE_FROM_QT4 instead, to make it clearer when reading the code
that the code in question was a left-over from Qt4, when we used
Q_WS_ defines instead of Q_OS_ defines.
This worked well for cases of #ifdef Q_DEAD_CODE_FROM_QT4, but less so
for cases of #ifndef Q_DEAD_CODE_FROM_QT4, where the code was actually
unconditionally included.
To make this even clearer, the defines have been replaced by checks for
1 or 0, with a comment describing how the code used to look in Qt4. The
use of constants in the check also makes it easier for editors to parse
the condition and show visually that the code is defined out.

windows and xcb enables SwitchableWidgetComposition meaning that widget
backing stores will fall back to the normal flush path when no render-to-texture
widgets are visible anymore in the window. This switch however can lead to
artifacts with the image of the rtt widget remaining visible until the next
full bacinkgstore sync. The safe and simple way around this is to do the
switch only in the next flush, keeping the flush where the switch is
discovered on the OpenGL-based composition path still.

Whenever a regular QWidget contains a child render-to-texture widget
(like a QOpenGLWidget) that is opaque (attribute
Qt::WA_OpaquePaintEvent is set) and completely covers the parent
geometry, the child widget would not be shown.
This happens because QWidgetBackingStore::doSync contains a check to
see if an opaque child completely covers its parent, in which case it
does not draw the parent, and only draws the child.
This is an issue if the widget is actually a texture-based one, because
for it to be seen on screen, the parent widget has to be redrawn with a
proper blending mask, so that the rtt widget gets properly composed
into the place where the mask is.
The fix consists in keeping the parent widget being marked dirty, in case
it has an opaque texture-based child that completely covers it. This will
force a redraw of the parent widget with a proper blending mask.

The performance optimization of falling back to flushing windows the normal
(raster) way once no render-to-texture widgets are visible has issues with
fullscreen windows, presumably due to the compositor's special handling of
such windows. Disable our smartness and stick with composeAndFlush for
ever in case the window is fullscreen.
