Owen Taylor 1472462639 Use floor() instead of truncating to integer values so we get translation
Wed Jan 20 11:19:00 1999  Owen Taylor  <otaylor@redhat.com>

	* gtk/gtklabel.c: Use floor() instead of truncating
	to integer values so we get translation invariance.

	* gtk/gtklayout.c (gtk_layout_size_allocate): Set upper
	and lower values for adjustments in size_allocate().

	* gdk/gdkwindow.c gdk/gdk.h gdk/gdkprivate.h: New
	function gdk_window_set_static_gravities() to set
	up a window for guffaw scrolling.

	* gdk/gdkwindow.c (gdk_window_internal_destroy): Set flags
	indicating destroyed state before cleanup.

	* gtk/gtkprivate.h gtk/gtkwidget.c: Add a new
	private flag IS_OFFSCREEN. If set, this indicates
	to GTK+ that the widget is not to be considered
	viewable regardless of its map state. Queued draws
	on offscreen widgets are suppressed.

	Added new function static gtk_widget_is_offscreen() to
	check this flag on a widget and its ancestors.

	* gtk/gtklayout.[ch]: Major revisions.

	- Use gdk_window_set_static_gravities to set static gravity
	on all child windows, and thus avoid having to create a window
	for NO_WINDOW children.

	- Adjust allocations of children as we scroll them
	so queued draws work correctly.

	- Don't allocate our children directly in a put()
	or move(); just queue a resize() like every other
	widget.

	* gtk/testgtk.c: Make the arrows on the scrollbars
	work, create a larger and more demanding test.
