Are there definitions of WM_MOUSEACTIVATE return codes such as MA_NOACTIVATE?

Is your feature request related to a problem? Please describe.

I looked in the source code and they're mentioned in comments, but I can't find any definitions for these constants.

Describe the additions or enhancements you'd like

Just add them, if they don't exist yet.

public enum MouseActivateCodes : int
{
   MA_ACTIVATE = 1,
   MA_ACTIVATEANDEAT = 2,
   MA_NOACTIVATE = 3,
   MA_NOACTIVATEANDEAT = 4
}
