Lo and behold, I managed to get Trillian to work past the splash
screen.  A bit early for a christmas miracle, but there it is :-).

This is, as far as I know, the first time anyone has gotten Trillian
to run with Wine CVS HEAD since late 2004.  That's about two years.

It also marks another historic event:  This is the first time in my
life that I've ever rejoiced upon hearing one of those lame
application startup sounds ;-).

This is the diff against wine 0.9 which makes it possible:

+    return;
+    // commenting next line out WILL fix Trillian.
    if (maxSize) *maxSize = MinMax.ptMaxSize;
+    // commenting next line out doesn't fix.
    if (maxPos) *maxPos = MinMax.ptMaxPosition;
+    // commenting next line out WILL fix Trillian.
    if (minTrack) *minTrack = MinMax.ptMinTrackSize;
+    // commenting next line out doesn't fix.
    if (maxTrack) *maxTrack = MinMax.ptMaxTrackSize;
 }

The patch should be self explanatory.
It just returns a bit earlier in WINPOS_GetMinMaxInfo, which seems to be where
things get screwed up.

I don't think this issue explicitly has anything to do with alpha transparency,
as was earlier indicated.

The two error messages from the original issue description:
 err:clipping:CLIPPING_UpdateGCRegion hVisRgn is zero. Please report this.
 err:local:LOCAL_GetBlock not enough space in GDI heap 10bf for 28 bytes
also does not appear in Wine 0.9, but the splash screen jerkiness does (without
above patch).
