More investigation shows that the only way to have the backing of the window to
be considered to have alpha information is 1) to have it visible on screen and
2) have -setOpaque:NO and -setBackgroundColor:[NSColor clearColor] on the
window 3) have the webview properly draw with transparency.

So in a nutshell, it's a complex fix for an unclear reward.
