[PATCH 0/3] MR9549: ddraw: Remove WS_CLIPCHILDREN when going fullscreen.

[Rémi Bernon (＠rbernon)]

Using a new wined3d WINED3D_NO_CLIP_CHILDREN flag which will remove the
style, as native, to allow win32u offscreen rendering to blit over child
windows but still invalidate them after WM_PAINT, as necessary for some
game such as Command & Conquer 2 to refresh their display properly.
