Fix

I've tested the demo.

The launcher is getting confused by zero window coordinates passed to
WM_NCCALCSIZE  when SetWindowPos() is called from SetWindowRgn(). Zero
coordinate are passed to WM_WINDOWPOSCHANGING in WINPOS structure both under
Windows and Wine, but WM_NCCALCSIZE is different.

I am attaching the patch which is fixing it.

While that fixes the launcher, the demo still does not start. Choosing 'Start'
runs some DRM config / launcher, when selecting 'Ok' there it registers some
services and then fails:

003f:fixme:ntoskrnl:PsSetCreateThreadNotifyRoutine stub: 003405C0
wine: Unhandled page fault on read access to 0xffffffff at address 00359C07
(thread 0045), starting debugger...
0034:err:service:process_send_command service protocol error - failed to read
pipe r = 0  count = 0!
0032:err:module:LdrInitializeThunk "MOSSFL.DLL" failed to initialize, aborting
0032:err:module:LdrInitializeThunk Initializing dlls for L"C:\\mos\\Mos.exe"
failed, status c0000142

Then those services continued to crash during each "boot" of Wine prefix until
I removed them manually (while it is really better to delete such Wine prefix).

The demo itself didn't work for me on Windows 7 either. There was no crash upon
attempt to start the game itself, but it silently closes. Maybe it needs to be
run as administrator, but I did not try that.

So if this demo really works on Windows somehow (or a full game does) but does
not work under Wine these further issues deserve a separate bug report.
