[ros-svn] [navaraf] 13366: Attempt to solve the imfamous WM_NCPAINT handle leak. The message handler isn't required to delete the region handle while it's also valid to delete it (eg. by calling GetDCEx with it). Thus we have to send the WM_NCPAINT message only synchronously and verify the handle after the SendMessage call.

Attempt to solve the imfamous WM_NCPAINT handle leak. The message handler isn't required to delete the region handle while it's also valid to delete it (eg. by calling GetDCEx with it). Thus we have to send the WM_NCPAINT message only synchronously and verify the handle after the SendMessage call.
