Thu Nov 27 2003  Arnaud Charlet  <charlet@act-europe.fr>

	* gtk/gtktextview.c (incremental_validate_callback): Increase amount
	of characters validated at each call, this gives a better behavior
	when loading big files.

	* gtk/gtktextbtree.c, gtk/gtktextiter.c: Remove some function calls
	when assertions are disabled.

	* gtk/gtktextlayout.c: Use local buffer to avoid dynamic memory
	allocation.

Wed Oct 15 2003  Arnaud Charlet  <charlet@act-europe.fr>

	* gtk/gtktextview.c (gtk_text_view_scroll_[h]pages): Undo
	1.216.2.12 change, since this is creating a regression in the
	handling of scrolling (#78513)
