bug#7412: 24.0.50 and 23.2.*; Cursor disappears over embedded images in recent --with-ns emacs

[ken manheimer]

In recent emacs (23.* and 24.0) on Mac OS X snow leopard, built using

"./configure --with-ns", the text cursor disappears when it is over

embedded images.

To reproduce the problem, substitute a path to the frown.xpm on your

system in the following and evaluate it:

(insert-image

  (create-image "/usr/local/share/emacs/23.1.90/etc/images/smilies/frown.xpm"

  'xpm))

Then move the cursor over the resulting frown smilie, and all traces of

the cursor will disappear.  The cursor will reappear if you move it off

of the frownie.

This problem occurs whatever shape I assign to cursor-type.

I've experienced this problem with checkouts built from the trunk as of

today (Nov 15, 2010) and the tag EMACS_23_2, and i also see it when

using the "Emacs for OS X Modified" downloaded from

http://vgoulet.act.ulaval.ca/en/ressources/emacs/mac (23.2.50).

Perhaps a related problem: setting the foreground color of the cursor

with 'customize-face cursor' face has no effect - the foreground color

of text under the cursor is always the same as the text when it is not

covered by the cursor.  Setting the background color does what it is

supposed to do.
