[PATCH 0/1] MR3416: ieframe: Forward WM_PAINT messages to the document host and all its child windows.

[Torge Matthies (＠tmatthies)]

Windows gives this content special protection from being painted over, by some means that I have not investigated yet.
Emulate this protection for the trivial case of an InvalidateRect(...); call on the parent window.
