+This constant defines the ratio that determines the amount of hysteresis between heap growing and heap
+shrinking.
+It is a 32-bit fixed point number where the radix point is defined to be
+between bits 7 and 8 (where the LSB is bit 0) i.e. using standard notation, a Q8 or a fx24.8
+fixed point number.  For example, for a ratio of 2.0, set KHeapShrinkHysRatio=0x200.
+
+The heap shrinking hysteresis value is calculated to be:
+@code
+KHeapShrinkHysRatio*(iGrowBy>>8)
+@endcode
+where iGrowBy is a page aligned value set by the argument, aGrowBy, to the RHeap constructor.
+The default hysteresis value is iGrowBy bytes i.e. KHeapShrinkHysRatio=2.0.
+
+Memory usage may be improved by reducing the heap shrinking hysteresis
+by setting 1.0 < KHeapShrinkHysRatio < 2.0.  Heap shrinking hysteresis is disabled/removed
+when KHeapShrinkHysRatio <= 1.0.

+/**
+Creates a heap in an existing chunk, offset from the beginning of the chunk.
+
+This function is intended to be used to create a heap using a chunk which has
+some of its memory already used, at the start of that that chunk.  The maximum
+length to which the heap can grow is the maximum size of the chunk, minus the
+data at the start of the chunk.
+
+The offset at which to create the heap is passed in as the aOffset parameter.
+Legacy heap implementations always respected the aOffset value, however more
+modern heap implementations are more sophisticated and cannot necessarily respect
+this value.  Therefore, if possible, you should always use an aOffset of 0 unless
+you have a very explicit requirement for using a non zero value.  Using a non zero
+value will result in a less efficient heap algorithm being used in order to respect
+the offset.
+
+Another issue to consider when using this function is the type of the chunk passed
+in.  In order for the most efficient heap algorithms to be used, the chunk passed
+in should always be a disconnected chunk.  Passing in a non disconnected chunk will
+again result in a less efficient heap algorithm being used.
+
+Finally, another requirement for the most efficient heap algorithms to be used is
+for the heap to be able to expand.  Therefore, unless you have a specific reason to
+do so, always specify aMaxLength > aMinLength.
+
+So, if possible, use aOffset == zero, aMaxLength > aMinLength and a disconnected
+chunk for best results!
+
+@param aChunk        The chunk that will host the heap.
+@param aMinLength    The minimum length of the heap in bytes.  This will be
+                     rounded up to the nearest page size by the allocator.
+@param aOffset       The offset in bytes from the start of the chunk at which to
+                     create the heap.  If used (and it shouldn't really be!)
+                     then it will be rounded up to a multiple of 8, to respect
+                     EABI 8 byte alignment requirements.
+@param aGrowBy       The number of bytes by which the heap will grow when more
+                     memory is required.  This will be rounded up to the nearest

+    key:
+
+    \snippet doc/src/snippets/declarative/keys/keys-pressed.qml key item
 
     Some keys may alternatively be handled via specific signal properties,
     for example \e onSelectPressed.  These handlers automatically set
     \e event.accepted to true.

+\class QDeclarativeTextLayout
+\brief The QDeclarativeTextLayout class is a version of QStaticText that works with QTextLayouts.
+\internal
+
+This class is basically a copy of the QStaticText code, but it is adapted to source its text from
+QTextLayout.
+
+It is also considerably faster to create a QDeclarativeTextLayout than a QStaticText because it uses 
+a single, shared QPainter instance.  QStaticText by comparison creates a new QPainter per instance.
+As a consequence this means that QDeclarativeTextLayout is not re-enterant.  Adding a lock around 
+the shared painter solves this, and only introduces a minor performance penalty, but is unnecessary 
+for QDeclarativeTextLayout's current use (QDeclarativeText is already tied to the GUI thread).
