Creates a layout object set up to match the current transformation
and target surface of the Cairo context.
This layout can then be
used for text measurement with functions like
[method@Pango.Layout.get_size] or drawing with functions like
[func@show_layout]. If you change the transformation or target
surface for @cr, you need to call [func@update_layout].
This function is the most convenient way to use Cairo with Pango,
however it is slightly inefficient since it creates a separate
PangoContext object for each layout. This might matter in an
application that was laying out large amounts of text.
