Is it supported? Full and/or partial?
Alpha Compositing on a 0.0 - 1.0?

hi,
on Windows (at least 2000) it is possible to set a global alpha value for the whole skin windows (but not on linux). Inside a skin window, full transparency between elements (image, button, etc.) and the window background is not supported, except for text (it is needed for anti-aliased fonts), because alpha-blending is quite CPU consuming, and anyway it is not really needed (there is a discussion about that in viewtopic.php?t=13666)[/i]

Thanks for the quick response. I still have a few questions though.
If I use a global alpha channel for a window, would I be able to
vary the degrees of transparencies? The phrase "If you can't make
it, fake it" comes to mind.

I'm under the understanding that VLC uses a XML base to string
together the elements, would it be possible to for instance, set
multiple layers of a global transparency. For instance if elements
are layered more heavily the "right corner" would the right corner
end up less opaque than the rest of the window? Would something
like that be possible with png bitmaps?
