Yes, the code now uses two loops, but it's slightly better than
erasing-during-iteration; the alternative is using e.g. a while loop and
advancing an iterator manually with operator++() (in two separate
locations, since there would be a `continue` statement) or with the
return value of QList::erase (in one location).

Setting color scheme before handling theme change provides incorrect
palette color when user switches from light to dark or dark to light.
This is visible when using Fusion style (or other style that supports
dark mode) in Windows. The change has been made as part of patchset
787038bb1d.
It also has to be noted that handling palette changes to make further changes to the palette (or the style sheet), is less likely than
Handling the colorScheme change signal and in this sense, this patch set
can also be considered as an improvement.
This patchset reverts that change and updates color scheme after palette change in the application.

Make it so that what we query with regards to 1.1, 1.2, and 1.3 features
are stored for later use. This will be relevant for e.g. multiview where
the multiview field will need to be checked when deciding if the feature
is supported at run time.
All this is only really compatible with Vulkan 1.2 and newer. Vulkan 1.1
does not have the 1.2 approach, i.e. there is no
VkPhysicalDeviceVulkan11Features
in Vulkan 1.1 (!). That is a struct added in Vulkan 1.2. In 1.1 one had
the feature (extension) specific structs, such as
VkPhysicalDeviceMultiviewFeatures
in case of multiview. That we do not bother with at the moment.
Then again that's nothing new. The existing code to enable all features
with a few exceptions, that's already tied to the 1.2+ way of working
with physical device features, and not quite compatible with a pure

Our logic in the edit menu tap recognizer for determining whether the
tap should trigger the edit menu only looks at the bounds of the input
area, and as long as the tap is within these bounds we trigger the edit
menu.
This doesn't take into account that there might be controls laid on top
of the input area, for example a button, where we don't want to trigger
the gesture.
The only related logic we have is a heuristic that checks whether the
cursor ends up moving as a result of the initial press, in which case
we treat it as the edit area "accepting" the touch press.
The proper fix to this is to handle the gesture recognizer delegate
callback gestureRecognizer:shouldReceiveTouch:, and do hit testing
there, but we don't have any machinery for that in our IM protocol,
nor in QWSI.
As a workaround, we treat the gesture recognizer as having failed,
even when we do detect a tap that should open the menu, so that the
recognizer doesn't eat the touch event. We then open the menu manually
instead of relying on the gesture recognizer changing state. This
should be safe, as sending a touch/mouse event down to the input
area should normally be a noop.
The workaround does result in a slight visual wart when clicking
buttons that live inside input areas, as the edit menu temporarily
opens, but the menu is quickly hidden again as the focus object is
transferred to the button. Compared to the current situation, where
the button is visually pressed, but doesn't do anything, and we
bring up the edit menu fully, this is an improvement, even with
the wart.
Note that the original problem outlined in this changed is not an
issue in practice for Qt Widgets, as we synthesize mouse events
from touch events, and (wrongly) synthesize a mouse release in
response to the touch cancel triggered by the gesture recognizer,
so the button is still activated.

It's not a real leak in that the string data is being freed on program
exit (or, more recently, QPixmapCache::clear()), but it can lead to
lots of memory being bound for much longer than expected when users
put in new QString keys without attempting to retrive them again. It
can also lead to problems with QStringLiterals lingering around until
after their underlying data has been freed. A bug in the Fusion style,
generating new string keys for identical state, exposed this
misbehavior, and one way to fix the resulting issue for the user is to
make sure that QPixmapCache doesn't leak QString keys.
The Fusion style issue with generating non-repeating keys for use with
QPixmapCache should also be fixed, eventually, but this patch
relegates that to an optimization issue (the caching is effectively
non-existent), the resource exhaustion is gone now.
The issue exists because the QString keys are internally mapped to
QPixmapCache::Key's by way of a QHash<QString, Key> cacheKeys data
structure. When the QCache, indexed by Key, not QString, decides to
evict an entry, the Key is invalidated, but no-one was removing the
corresponding entry from cacheKeys. So make the existing releaseKey(),
used to invalidate copies of Keys referring to evicted pixmaps, do
that, now. So as not to have to scan the whole cacheKeys QHash for the
right Key, store the QString key, if any, inside the Key, so
releaseKey() can retrieve it and use it for O(1) erasure from
cacheKey.
This allows removing the previous work-around in clear()
(6ab0d25a09), greatly simplify
object(QString), and requires to rewrite all code that holds iterators
or references into cacheKeys over an insertion into or removal from
the QCache. Two (insert() and remove()) have already been done in
prequel commits, so only flushDetachedPixmaps() was left.
