title: How to set TPanel transparent?
body: <p>When placing the <code>TPanel</code> component in designer, it seems it can not be made <code>transparent</code>? There's an opacity option, but that only deails with animations. I want the panel itself to be fully transparent, so I can see the image underneath. (I want to use the panel as a way of control layout of the controls placed on it)</p>
