patch: bug #4831 part 2

[Will Roberts]

Hello:

This is my first patch submission to Emacs.  I'd be happy to learn how to do it 
better in the future, if you have any comments or criticism.  The patch was 
made against the bazaar repository.

Thanks,
Will

== Description: ==

A first draft at patching bug #4831 (23.1.50; cursor problems on Mac OS X), 
specifically part 2, where characters under the cursor are not seen.

Modified the drawing routines: 
* the cursor will be drawn with the frame foreground color if the cursor color 
is the same as the current face background color or the frame background color.
* the text over the cursor will be drawn with the frame background color if the 
cursor is a filled box, and the cursor color is the same as the text color

you like.
