HACK: Blit ddraw surface to window at (1,1)

Seems that many of the older hacks don't work anymore (or need gdi32 renderer),
so here's a new one. Works with Wine 2.0-rc2 and probably any later versions as
well.

This hack copies ddraw surface to the window at (1,1) when the ddraw surface is
unlocked. This needs to be enabled with DDRAW_HACK=1 on runtime, so this
doesn't interfere with other applications.

This works at least for Diablo (partially, not neatly).
