I'm having trouble setting WS_EX_LAYERED (0x80000) flag on the Canvas
window. I can see thru spy++ that the flag wasnt set. Is there something
I'm missing?
int extStyle = OS.GetWindowLong(canvas.handle, OS.GWL_EXSTYLE);
extStyle = extStyle | 0x80000;
OS.SetWindowLong(canvas.handle, OS.GWL_EXSTYLE, extStyle);

It doesnt seem to work for me. Would it be because the canvas is a child
window of the Shell that I'm running it in?
