Nyall Dawson 61009bdf95 [feature] Add auto-wrap after setting for layout legends
Allows legend text to be automatically wrapped after a set
line length (in millimeters).

This can prevent very wide auto-generated legends.

public:
QgsLayoutItemRenderContext( QgsRenderContext &context, double viewScaleFactor = 1.0 );
%Docstring
Constructor for QgsLayoutItemRenderContext.
The ``renderContext`` parameter specifies a :py:class:`QgsRenderContext`
for use within the QgsLayoutItemRenderContext.
The ``viewScaleFactor`` gives the current view zoom (scale factor). It
can be used to scale render graphics so that they always appear a
constant size, regardless of the current view zoom.
%End
QgsRenderContext &renderContext();
%Docstring
Returns a reference to the context's render context.
Note that the context's painter has been scaled so that painter units
are pixels. Use the :py:class:`QgsRenderContext` methods to convert from
millimeters or other units to the painter's units.
%End
double viewScaleFactor() const;
%Docstring
Returns the current view zoom (scale factor). It can be used to scale
render graphics so that they always appear a constant size, regardless
of the current view zoom.
E.g. a value of 0.5 indicates that the view is zoomed out to 50% size,
so rendered items must be scaled by 200% in order to have a constant
visible size. A value of 2.0 indicates that the view is zoomed in 200%,
so rendered items must be scaled by 50% in order to have a constant
visible size.

Attempts to resize the item to a specified target ``size``. Note that

items with a fixed or minimum size will place restrictions on the
allowed item size. Data defined item size overrides will also override
the specified target size.

Attempts to move the item to a specified ``point``.
If ``useReferencePoint`` is ``True``, this method will respect the
item's reference point, in that the item will be moved so that its
current reference point is placed at the specified target point.
If ``useReferencePoint`` is ``False``, the item will be moved so that
``point`` falls at the top-left corner of the item.
If ``includesFrame`` is ``True``, then the position specified by
``point`` represents the point at which to place the outside of the
item's frame.
If ``page`` is not left at the default -1 value, then the position
specified by ``point`` refers to the relative position on the
corresponding layout ``page`` (where a ``page`` of 0 represents the
first page).
Note that the final position of the item may not match the specified
target position, as data defined item position may override the
specified value.

the current item rotation.

virtual double estimatedFrameBleed() const;
%Docstring
Returns the estimated amount the item's frame bleeds outside the item's
actual rectangle. For instance, if the item has a 2mm frame stroke, then
1mm of this frame is drawn outside the item's rect. In this case the
return value will be 1.0.
Returned values are in layout units.

%Docstring
Returns the item's rectangular bounds, including any bleed caused by the
item's frame. The bounds are returned in the item's coordinate system
(see Qt's QGraphicsItem docs for more details about QGraphicsItem
coordinate systems). The results differ from Qt's
:py:func:`~QgsLayoutItem.rect` function, as
:py:func:`~QgsLayoutItem.rect` makes no allowances for the portion of
outlines which are drawn outside of the item.

Draws the item's contents using the specified item render ``context``.

Applies any item-specific size constraint handling to a given
``targetSize`` in layout units. Subclasses can override this method if
they need to apply advanced logic regarding item sizes, which cannot be
covered by :py:func:`~QgsLayoutItem.setFixedSize` or

Refresh item's opacity, considering data defined opacity. If

Refresh item's frame, considering data defined colors and frame size. If

Note that item subclasses should not rely on all other items being
present in the layout at the time this method is called. Instead, any
connections and links to other items must be made in the

restoring a scalebar, the connection to the linked map's signals should
be implemented in :py:func:`~QgsLayoutItem.finalizeRestoreFromXml`, not
