* gtk/gtkwidget.c (gtk_widget_draw): Ignore calls with
<= width or height.
* gtk/gtktable.c (gtk_table_attach): Fix missed merge
from 1.2 for parent/child states.
* gdk/gdkgc.c (gdk_gc_set_rgb_fg/bg_color): Fix a couple
of typos.
* gdk/gdkevents.[ch]: Remove press/xtilt/ytilt fields of
event structures, replace with a generic axes field. Replace
deviceid/source with GdkDevice *device.
* gdk/gdkevents.[ch] (gdk_event_get_axis): Add function
to extract particular axis use value from event. (Also
can be used for normal X/Y.)
* gdk/gdkinput.h gdk/x11/gdkinput*: Major revision;
allow for arbitrary number of axes, namespace everything
as gdk_device_*. Replace guint32 deviceid with GdkDevice *
everywhere.
* gdk/x11/{gdkmain-x11.c,gdkevent-x11.c,gdkinput*}:
Get rid of the gdk_input_vtable setup if favor of simply
defining the functions in gdkinput-none/gxi/xfree.c in
a similar fashion to the way that the port structure is
done.
* gtk/gtkdnd.c: Fix fields of synthesized button press event
for new event structures.
* gtk/gtkinputdialog.c gtk/testinput.c: Revise to match
new device interfaces.
