While reading Georg Nikodym's screen shot, I noticed that the Lucid
scrollbars work quite well.  I could scroll the up the buffer one line
at a time and the inlined image would have an extra lines worth of
image to show.  Of course, when there were no more text lines to be
shown, pressing the down arrow on the scrollbar jumped to the "next"
line and showed the bottom of the image.

So, for the most part the scrollbar did the right thing.  What I'm
wondering is if it were possible for the scrollbar to scroll by a
nominal amount even if the apparent line height was very large.
Something like if nominal-line-height set, then scroll image by the
nominal-line-height.  Otherwise, scroll by physical lines.  The
default being nominal-line-height being unset.

This may not be exactly right, but it seems that it would do the job
99% of the time.

I'd try to do this myself, but I don't speak X or XEmacs internals.
Bummer.  :-(
