Bisect log

Starting with Wine 1.5.18, Atlantica Online is no longer playable due to a bug
where if you attempt to rotate the camera with the mouse (right-click and
drag), Atlantica's graphics lock up and the game seems to lose the mouse.  You
can get the game to respond again by pressing alt on the keyboard, but you
still can't rotate the camera (or rather not much, it'll move a tiny bit each
time before locking up).

I went ahead and bisected this, and also ran into a problem where Atlantica
never got control of the mouse/keyboard and had to be closed with alt-f4.  In
these cases I used 'git bisect skip' to continue.  Git finally came up with 18
possible "bad commits".  Looking at them in gitk, the following commits are of
note (the first skipped commit and the first known bad commit):
841214ddb4d4dc620e6b51dfe6655b585d423edc - user32: Don't check for driver
events before normal messages in PeekMessage.
a0f039a6049641cc2be8fa32f2afa3c3f394a99b - user32: Fix the wait event mask in
PeekMessage.

The first of these commits caused Atlantica to not respond much to
mouse/keyboard events (you could get a partial response from the mouse if you
could get it over a button, but you can't see the pointer), and while the
second patch fixed that, attempting to rotate the camera using the mouse causes
Atlantica's input/graphics to partially freeze as noted above.

I've attached the bisect log so that you can have a look at it if you need to.
