Alpha channels support?

[Nanaki 0]

Well, I have a simple Pic control and I want it to respect the appropiate alpha channel (BMP and GIF). Is it possible? Like, when the app is launched on the desktop, it shows parts of the desktop where alpha.

And, PNG's won't work. Again, it's a simple GuiCtrlCreatePic, are they supported? JPG, BMP and GIF work fine.
