Recently I found a bug (which is different from Bug#17114) in drawing
images with box on the Mac port, and I suspect it also happens on W32
because their code are similar (though I can't test it). Could
someone try if it is reproducible on W32 and if so, please try the
patch at the end?
Steps to reproduce:
1. $ emacs -Q -D &
2. (insert-image (create-image "splash.png")
(propertize " " 'face '(:box (:line-width 5)))) C-j
3. C-p C-p
Result:
The left half of the character `t' just after the image gets erased.
