Evaluate the form below, 10 images are inserted in one logical line.
The fourth image of the first visual line and the fourth image of the
secodn visual line are hidden partially at the right edge of the window,
where (frame-char-width) => 8 and (window-text-width) => 80.
Also #'previous-line works strangely.
>From the end of the 3rd visual line(next to the 2nd image of the line),
type C-p, then the point moves to the 3rd image of the 2nd line,
type C-p, then the point moves to the 1st image of the 2nd line,
type C-p, then the point moves to the 3rd image of the 1st line,
type C-p, then the point moves to the 1st image of the 1st line,
type C-p, then the point moves to the column of the previous line near
the 3rd image.

I've looked at the code: it's deliberate. We truncate the image to
fit within the window, but still leave the margins around it.
So I don't see what else needed to be fixed here, and I'm closing this
bug report.
