forked from AuroraMiddleware/gtk

Added a few apis,
- GtkCellAreaContext get_preferred_height_for_width &
width for height apis and vfuncs, this lets the icon view
request the collective (and aligned) height for width for
a said row.
- gtk_cell_area_copy_context() this creates a duplicate of
an already created and requested context, this way the icon
view uses a global context to request the widths of all rows
and then makes a copy with all the stored alignments and
uses a separate copy to calculate the height and alignments
of each row separately.
