In case a text to be layouted contains more than 128 directional characters
it causes the application to crash
The function initScriptAnalysisAndIsolatePairs() collects information of
RTL/LTR chaaracters into vector "isolatePairs". The size of the vector is
capped to 128. Later the function generateDirectionalRuns() iterates
the text again and tries to access items from the previously capped vector
above the upper bound.

When calling QTextDocument::clearUndoRedoStacks() with UndoStack,
there were two bugs: The first was that we were retrieving
the item at "undoState" and deleting this. This is actually the
upper limit of the for loop. If the stack does not contain any
redos, then it would be == undoStack.size() and we would assert.
If there were redos, then we would delete the item at undoState
multiple times (actually undoState times).
In addition, when the loop exited, we first removed the dangling
pointers using remove() and then there was a weird resize() to
the new size minus the old undoState.
This would either assert because we tried to resize to a negative
number, or it would arbitrarily remove items from the stack.
[ChangeLog][QtGui][Text] Fixed a crash bug in
QTextDocument::clearUndoRedoStacks(QTextDocument::UndoStack).

The newly introduced clear() method left the path in an undefined
state: d_ptr allocated, but no elements. The elements vector is
otherwise never empty, since ensureData() inserts a dummy initial
moveTo element.
Fix by making sure that clear() leaves the path in the same state as
ensureData() (i.e. "empty" but not "null"), except possibly more
capacity allocated in the elements vector.

If the start position of a backward string search was the at the start

The QBrush constructor taking a QGradient would assert or crash if
passed a null (NoGradient) gradient. But it is not necessary for the
API to be as brittle as that: instead the result can simply be a null
QBrush object, i.e. the same as the default QBrush() constructor
creates (style == NoBrush).
This issue comes up now since with the recent introduction of
QGradient presets, the API opens for using QGradient directly, whereas
earlier, only the subclasses QLinearGradient etc. were to be used.

In 3ccdeb4b58, we removed the
specialized multi font engine on Windows, causing us to go
through the same code path when loading fallbacks as on
other platforms.
When combined with 97f73e9577,
this caused an error, because the code in
QFontEngineMulti::loadEngine() only overrode the families
list, but not the singular family in the request. In the
QRawFont test, this would cause the requested fallback font
to correctly have "MS Shell Dlg2" as the only font in the
families list, but the request.family would still be
"QtBidiTestFont", the name of the main font. The singular family
in the request was preferred by the windows font database when
creating the LOGFONT. We would therefore load the latter for
the fallback as well and since it still does not support the
characters in question, we would continue searching.
