Some new parskip possibilities had been added, but the check for
custom length index had not bee updated.
This code is very fragile.
Related to bug #10968.
Rather than that, keep it with a warning that it is not available.
Fallback procedure (which maintains security measures) is done in
the conversion step.
This prevents document properties being silently changed on sharing.
The QWinMime class has been removed in Qt6 but the functionality
is still present. However, one has to allow inclusion of private
headers and register the mime handling to the QWindowsApplication
native interface.
Those checks might not be needed, but it's not self obvious from
the surrounding code. Because we already experienced crash from
similar change (cf 1c1c83eced96), let's be prudent here.
If you know that these pointers can't be null from broader context
feel free to remove the guards.
Introduced by 24926b2e2399, fix 104fdcc9be40df1 not backported
but now fixed by 1c1c83eced96 in 2.3.

Add parameter 'force' to scrollToCursor(...) to avoid the case where the
cursor is not set to top because it is already visible on screen.
Change screen offset in this method so that the paragraph is really at
the top of the screen. This part may cause unforeseen issues and needs care.
gotoInset: use the new force flag and do not trigger a redraw.
Instead, return a boolean telling whether redraw is needed.
In the code that use it, set an update flag instead of the extra redraw.
In the handling of paragraph-goto, also set the update flag instead of
triggering a repaint.
Remove Bufferview::scrollToCursor(), which was equivalent to showCursor().
Fixes bug #10425.
Lyx crashes on export to pdf if used with sanitizer set to 'unspecified'.
Crash found by Scott.
Given that if we export without GUI, there is some weirdness here though.
1.) Why does lyx not crash if not using '-fsanitize' compile-option
2.) Why is export to pdf dependent on the screen-resolution
This fixes two performance issues and improves the performance of
TextMetrics::redoParagraph by 15% in a workload that uses the cache a
lot. The difference will be much less when the cache is not used much.
1/ repetion of the hash code computation
The code
if (cache.contains(key))
result = cache[key]:
is not efficient, since qHash(key) has to be computed twice.
To fix this a new Cache::object_str() method is added, which allows
if (auto * obj = cache.object(key))
result = *obj;
2/ code of has code computation
Instead of using a verbose string that is complicated to build as
key, new key structs BreakAtKey and TextLayoutKey are introduced,
along with the relevant qHash() implementation.
Initially Qt5 modifier handling was broken. Therefore a workaround was introduced.
This workaround broke the LyX modifier handling with swap of Command-Control-key disabled.
The change disables the hack to get the correct behavior in LyX.
