WS_EX_TRANSPARENT bug

[Felipe W Damasio]

Hi,

	First of all, I'd like to thank Tony Lambregts and Sander van Leeuwen 
for helping me.

	Tony: Since I tested and saw that Sander's patch fixed, I closed the 
bug. That patch should definitely enter on mainline!

	Anyway, I'm here to report another bug:

	CreateWindow's flag WS_EX_TRANSPARENT doesn't do anything.

	Cesar Mello did a little example program which uses this flag:

	Both source and an executable are available here:

ftp://ftp.elipse.com.br/pub/transp/transp-exe.tar.gz

ftp://ftp.elipse.com.br/pub/transp/transp-source.tar.gz

	I'll enter this bug on bugzilla right away.

	Does anyone can help me with this?

	Thanks,

Felipe

I would have added this to the bug, but I don't have access to my
bugzilla password right now (why oh why didn't i change it!). 

Anyway, we can't implement this currently, X11 doesn't support
transparent windows :(

Not quite true
See the following:

http://www.eax.com/render/#d4

Transparency galore!!

Note:
	One method only works of a CVS version of Xft/Xrender.
	extension(s?)
	The other works using the shape extension.

It's prossible, but not necessarily trivial
	-Rob.

P.S. Apologies to Mike, sent first version of this message Bcc Wine devel.

That's an interesting demo. In the source, I can't actually see where
the translucency is set.

Anyway, I know that although some prototypes were knocked up a few years
ago, it actually needs a translucent window extension which hasn't been
written yet (more hacking on the x internals needed)
