The transparence code - is it installed?

The transparence code - is it installed?

[Lennart Borgman (gmail)]

There was a question on EmacsWiki if the transparency code was installed:

   http://www.emacswiki.org/cgi-bin/wiki/TransparentEmacs

According to this

   http://lists.gnu.org/archive/html/emacs-devel/2008-06/msg00125.html

it is. But it does not work for me (with my patched Emacs on w32). What 
is the state now, is this patch installed? There is nothing in Info as 
far as I can see.

It is installed, but you'll need a compositing window manager (like
compiz or mac osx) to use it.

I've tried it, and it works, but it doesn't seem terribly useful in
practice -- afaict, it affects _everything_ in the emacs frame, not just
the background (and compiz, at least, can actually do that without any
emacs support at all)...

Then there is something strange. There were several people trying to 
make me add this to my patched Emacs for w32. What has happened to the 
w32 part? Was it lost somewhere?

This thread prompted me to try it myself as well, as I enjoy a slight
bit of translucency to my editing/shell workspaces.  And indeed, the
translucency of non-background elements is undesirable.

Are there any plans to add support for alpha channel values in the color
specifications?  It should be possible with GTK+ (the XFCE terminal
emulator uses true translucency for the background on composited
displays).
