-- The t'GI.Gtk.Objects.CellAreaContext.CellAreaContext' object is created by a given t'GI.Gtk.Objects.CellArea.CellArea'
-- implementation via its t'GI.Gtk.Structs.CellAreaClass.CellAreaClass'.@/create_context/@() virtual
-- method and is used to store cell sizes and alignments for a series of
-- t'GI.Gtk.Interfaces.TreeModel.TreeModel' rows that are requested and rendered in the same context.
-- 
-- t'GI.Gtk.Interfaces.CellLayout.CellLayout' widgets can create any number of contexts in which to
-- request and render groups of data rows. However, it’s important that the
-- same context which was used to request sizes for a given t'GI.Gtk.Interfaces.TreeModel.TreeModel'
-- row also be used for the same row when calling other t'GI.Gtk.Objects.CellArea.CellArea' APIs
-- such as 'GI.Gtk.Objects.CellArea.cellAreaRender' and 'GI.Gtk.Objects.CellArea.cellAreaEvent'.

-- is only allowed to grow (this is usually an option
-- for views rendering large data stores as a measure
-- of optimization), then only the row that changed
-- or was inserted needs to be (re)requested with

-- 
-- When the new overall size of the context requires
-- that the allocated size changes (or whenever this
-- allocation changes at all), the variable row
-- sizes need to be re-requested for every row.
-- 
-- For instance, if the rows are displayed all with
-- the same width from top to bottom then a change
-- in the allocated width necessitates a recalculation
-- of all the displayed row heights using
-- 'GI.Gtk.Objects.CellArea.cellAreaGetPreferredHeightForWidth'.
