picture from disk to be the background for a game. It seemed like an
easy way to accomplish it.

Thanks for the tip. By moving the DisposeDTObject() to after the
creation of the window, it's working now.

I admit I don't totally understand DoDTMethod and ProcLayout. Docs for
Datatypes are hard to come by. But at least the program working now!
It's in hicolor, so I don't need to remap it.
