	* configure.in (ACLOCAL): add code to save ACLOCAL_FLAGS

	* src/frames.c (meta_frames_expose_event): max dither

	* src/testgradient.c (render_simple): change dither mode to MAX
	to avoid banding

	* src/theme.c: lose the gradient cache, and put in some initial
	data types for the theme format

* configure.in (ACLOCAL): add code to save ACLOCAL_FLAGS
* src/frames.c (meta_frames_expose_event): max dither
* src/testgradient.c (render_simple): change dither mode to MAX
to avoid banding
* src/theme.c: lose the gradient cache, and put in some initial
data types for the theme format
2002-01-07 Havoc Pennington <hp@redhat.com>
* src/frames.c (meta_frames_expose_event): make gradient a bit
more subtle (don't go to the full background, but to a blend of
selection and background; put lighter color on top)
2002-01-06 Havoc Pennington <hp@pobox.com>
* src/window.c (meta_window_notify_focus): rearrange code a bit to
make it clear that has_focus flag always follows
display->focus_window
2002-01-06 Havoc Pennington <hp@pobox.com>
* src/window.c (meta_window_notify_focus): put in attempted fix
