What really happens with TransparentColor of TForm is that it takes a
screenshot of the screen, probably before the application is loaded,
so it doesn't appear on the screenshot, and the first thing that
happens on the paint process of the window is paint a portion of the
screenshot.
There is no real window transparency on Windows API. All apps that
don't seam to have a rectangular window acctually work like that.
I think SetWindowRgn makes part of a window transparent (the parts not
in the region). For example, winamp can do it: have oddly shaped sizes.
