	* gtk/gtktextlayout.c: use FALSE for size_only most
	of the time when calling gtk_text_layout_get_line_display()
	to avoid causing double reshapes when a redraw follows
	immediately after.

Tue Jul 11 11:13:40 2000  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtkrange.c (gtk_range_default_[hv]slider_update): Invalidate
	appropriate region and gdk_window_process_updates() so trough
	updating doesn't lag behind the window being scrolled.

        * gdk/gdkgc.c: Make parent_class pointer static.

Sun Jul  9 21:31:23 2000  Owen Taylor  <otaylor@redhat.com>

        * gdk/gdk-pixbuf.c gtk/gdk-pixbuf-loader.c gtk/gtktextview.c:
	include <string.h>.

	* gdk/gdkpixbuf-render.c (gdk_pixbuf_render_to_drawable): Fix
	cut-and-paste error in computing memory offset for 4 channels.
