    yes.

    > If I understand right, then this is a bug, as I previously said.

    i think i agree.  the only question i have concerns the resonsibility
    and disrcetion of the application developer.

I think we have a responsibility to make sure that the default way of
displaying an image does work properly with the cursor.  To have some
peculiar option which means the cursor does not display properly might
be excusable, but it's not excusable for the default to display wrong.

I suggested:

    That would be bad,  since it would change the geometry.
    What I think he proposed is to show the cursor over the outer parts
    of the image.  That seems good for this case.

Is anyone working on this?

* cursor doesn't show through transparent images in emacs 22, unlike emacs 21

i don't know how to get anything but the outermost pixels of the
cursor to show behind transparent images in emacs 22, while the cursor
body shows through the transparent part of images in emacs 21.

here's a fairly simple way to produce the effect:

  emacs -q

include the following text in the scratch buffer:

  (put-text-property 1 2 'display (find-image '((:type xpm :file "info.xpm"))))

evaluate the expression, and the first character in the buffer should
turn into the info question mark glyph.

put the cursor on the first character.  in emacs 22, only the
outermost pixel of the cursor shows.  in emacs 21, the cursor color
shows through everything but the question mark symbol, itself.

the info xpm images shipped with emacs 21.4 and 22.0.50 are identical.

is this a bug, or am i doing something wrong?
