I was told on IRC to "test as much as you can get tested", and
memcmp'ing the entire structure made me change my patch. Initially I had
Lock fill the entire structure as it did in Wine 9.35. But ok, Baldurs
Gate certainly only cares about lpSurface.

It does not change existing whitespace but adds two empty lines with
trailing whitespace. I'll resend without that.
