This mostly goes to keep consistency with the changes to GtkSizeRequest in the last patch, as GtkCellSizeRequest requires GtkCellRenderer and GtkCellRenderer implements GtkCellSizeRequest there's no use in keeping them separate. This patch renames the functions: gtk_cell_size_request_get_request_mode() => gtk_cell_renderer_get_request_mode() gtk_cell_size_request_get_width() => gtk_cell_renderer_get_preferred_width() gtk_cell_size_request_get_height() => gtk_cell_renderer_get_preferred_height() gtk_cell_size_request_get_size() => gtk_cell_renderer_get_preferred_size() gtk_cell_size_request_get_width_for_height() => gtk_cell_renderer_get_preferred_width_for_height() gtk_cell_size_request_get_height_for_width() => gtk_cell_renderer_get_preferred_height_for_width() ... and moves the corresponding vfuncs to GtkCellRenderer. The patch also renames the implementations of these functions in cell renderers to include the word "preferrred".
