* 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.
