Mass api change from GtkExtendedLayout --> GtkSizeRequest This commit makes a few massive changes to the extended layout code: a.) gtkextendedlayout.c --> gtksizerequest.c b.) _is_height_for_width --> get_request_mode() c.) get_desired_size(), get_desired_width(), get_desired_height() --> get_size(), get_width(), get_height() This is the first partial commit and only effects portions of the tree that have already been merged in master (in order to easily cherry pick this commit). Conflicts: gtk/Makefile.am gtk/gtk.h gtk/gtk.symbols gtk/gtkextendedlayout.h
