 subject: NIM: Handle WM_PAINT messages without update regions
 component: windows
 
 It is possible to receive a WM_PAINT message in Windows without there
 being an update region.  For example, this can be caused by someone
 calling RedrawWindow() with the RDW_INTERNALPAINT flag set.  In this
 case, GetUpdateRect() will indicate that there is no update region and
 calling BeginPaint()/EndPaint() results in incorrect behavior.
 
 The credentials window in Network Identity Manager needs to perform
 special handling for this case by obtaining a proper device context
 and completing the drawing operation.
