csOpaque is a hint which component gives to lcl whether it fully draws

To be fair, I did try and find help on csOpaque, but there was none. I then
searched the LCL and found the following code with comment. I assumed from
that, that csOpaque means the component will be transparent.
csOpaque:
- the control is treated as transparent
- but it does not make a control transparent
csOpaque is used by the LCL when clipping and mouse clicks.
Most LCL controls are not transparent and there is no flag to make
them transparent.
You can create transparent controls even TWinControls with childs, but
afaik nobody has yet created such a widget. And I guess you can only
get limited transparency. The easiest is to just paint the parent
background.
