Here is a patch to change the way the window is resized.
After applying the patch, more space will be given to
the display of audio data instead of the labels at the
bottom of the window.
I have tested it with gwc-0.20-07. It only changes two
lines of code and a similar thing can be done with
To apply the patch unpack a copy of gwc-0.20-07. Then
change into the "gwc-0.20-07" directory and use a
patch -p1 < gwc-0.20-07_with_different_spacing.diff
where "gwc-0.20-07_with_different_spacing.diff" is the
file name of this patch.
