Changes 2009-07-15/16 in branch?

[Adrian Robert <adrian.b.robert@gmail.com>]

Hello Yamamoto-san,

Did you mean to check the changes below into the branch?  I *think*  
these are pretty safe, but it seems a bit close to release for such  
feature changes, even in the name of standardization.  My vote would  
be to do these on trunk only for now.

Also:

ns_get_color(): Shouldn't the description comment for ns_get_color()  
be updated further?  It looks like something was just chopped off,  
leaving the rest making little sense.  What is the bug or problem this  
change fixes?

ns_color_to_lisp(): The function could be simplified now that you have  
eliminated a special case.

nsfont_draw(): Would setting the foreground instead of the background  
color to the bitmap constitute a corrected implementation?

ns-set-background-alpha: The implementation you just removed was  
superior to that for (set-frame-parameter nil 'alpha ##): it does not  
alter the alpha of the titlebar, scrollbars, modeline, or text.  This  
makes it usable, instead of a curiosity.  It also provides access via  
an interactive function.  The correct fix would be to improve the (set- 
frame-parameter) version, not remove this while no alternative exists  
for users.
