Wine debug output

Rendering in the Civilization III: Conquests game is really slow in the 1.5.10
version of wine - about 2-3 FPS. This is most likely related to the OpenGL DIB
engine introduced as per bug 30669 - the game was not rendering properly in
prior wine versions.

I have tried profiling, but with very limited success - I can't get valgrind to
work with wine, and sysprof reports high CPU usage in Xorg caused by copying
bitmaps around, with no further details. Xorg also has a 90%+ CPU usage while
the game is running.

I have tried both the integrated Intel card (Sandy Bridge) and a GeForce GT
555M through bumblebee, with identical results.

Attached a dump with WINEDEBUG=warn+all,+gdi,+dib,+opengl,+d3d,+ddraw - not
really sure what else I can do to diagnose the issue.

The problem is present in both the Steam and a NoCD version - the dump is from
the noCD one to eliminate any possible Steam interference.
