When the string we receive from the system doesn't parse into a valid
QUrl (because QUrl requires a valid IDN), then we shouldn't send the
QFileOpenEvent based on that invalid QUrl, but instead pass the string
through as the file name.
The file name is anyway not guaranteed to be path to a file that can be
opened, as per the existence of QFileOpenEvent::open and the repective
documentation stating:
"some files cannot be opened by name, but require specific information
stored in this event."
However, that API is not useful at all, the implementation just opens
the passed-in QFile, using the stored file name. There's no way
to override this, and QFileOpenEvent is a locked class with all data
stored inline. So we can't even redirect to a platform-implementation.
Deprecate that function. Applications should interpret the string
returned by file(), which might not be a path to a local file.

There's no need to try the various permutations of the language
and region specific locales, as they all point back to the same
CTYPE in /usr/share/locale/UTF-8/LC_CTYPE
In addition, processes started from launchd come with an empty
locale environment (LC_ALL/LC_*/LANG), and hence will default
to the "C"/POSIX locale, even after picking up the environment.
This primarily applies to applications launched from Finder,
but also affects processes launched as background services.
And since a child process will inherit its parent's environment
the empty locale environment is propagated when running apps
from IDEs such as Qt Creator or Xcode, or commands in an SSH
login session (as sshd is a background service), unless the
environment has been explicitly set up by the shell (Zsh).
Since neither of these situations is the result of user
misconfiguration, it makes little sense to spit our a
warning.
We however still warn if we detect that the character
encoding has changed from the default "C" encoding, or
if the encoding is "C", but we detect that the user has
modified any of the relevant locale environment variables,
as this indicates either a change in the system default
behavior, or that the user has explicitly requested a
"C" locale, which is wrong.

Also, the user is liable to understand "system locale encoding" as
referring to the underlying system rather than whatever they may have
configured in a local shell; and a non-native speaker assures me the
use of "shall" is also apt to confuse; so reword the messages.

...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

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).

Because the previous code in PolygonRegion() was:
Q_ASSUME(Count > 1);
But Q_ASSUME is becoming a no-op with GCC 12, so when this disappears,
compiler rightly considered Count < 2 as a valid input. Therefore, when
CreateETandAET() was called and had
if (count < 2)
return;
The compiler again rightly concluded that it was a valid condition
(after all, you're checking it!), leading to ET.ymax being used
uninitialized.
Since that Q_ASSUME really meant the condition of Count < 2 was not
permitted, we may as well upgrade to Q_ASSERT in both places.
