copyContext
This is sometimes needed for cases where rows need to share alignments in one orientation but may be separately grouped in the opposing orientation.
For instance, GtkIconView
creates all icons (rows) to have the same width and the cells theirin to have the same horizontal alignments. However each row of icons may have a separate collective height. GtkIconView
uses this to request the heights of each row based on a context which was already used to request all the row widths that are to be displayed.
Return
a newly created GtkCellArea
Context copy of @context.
Parameters
context
the GtkCellArea
Context to copy
