and move most of the COM functions to the DirectSoundDevice class.

- Separate WM_NCCREATE and WM_SETTEXT.

  control to the size of the bitmap/icon").
- Always call GlobalUnlock16 after GlobalLock16.

- Always paint the background of static controls displaying enhanced
  metafiles.
- Also paint the background if there's no metafile to display.

Use Heap[Alloc|Free] instead of malloc|free.

Added a new server call as PostQuitMessage should set a flag in the
message queue to return the WM_QUIT message when there are no other
pending messages, rather than posting a message to the thread queue as
it does at the moment.
