      winemac: Ignore clipboard updates provoked by our own call to GetClipboardData(). · c95d2de3
      Ken Thomases authored 
      During a call to GetClipboardData(), the app may be asked to render the data
for a promised format.  This will cause us to receive WM_CLIPBOARDUPDATE.

Almost always, the app will have just rendered the requested format and not
made any other changes.  Therefore, we don't need to rebuild the Mac pasteboard
from the Win32 clipboard.  Doing so can cause a race with the other Mac app
which is querying the pasteboard (for a paste operation, for example).  We
basically delete the data we _just_ added and rebuild the list of available
types.  The symptom is that the other Mac app sees the available types change
and maybe be incomplete.

In theory, the Windows app could make other changes to the clipboard and this
change would cause us to fail to convey them to the Mac pasteboard.  I consider
that very unlikely and the tradeoff to improve the common case is worth it.
