Output from the .NET Framework 2.0 installer

On the latest 0.9.55 release, easyC Pro and the .NET Framework 2.0 installer
hang after being started with wine easyC_Pro_3109.exe and wine dotnetfx.exe
respectively. These issues were not exhibited in 0.9.54. A Git bisect revealed
the regression in question to be:

comctl32: Get the background colour in ANIMATE_PaintFrame, instead of just
in WM_PAINT.

This fixes the rendering of transparent animations when using a
    background thread.

Invoking strace on the applications shows the app hung in a read() call, and
relay traces seem to indicate a hang in SendMessageW. While the easyC
application always hangs, the .NET Framework exhibits intermittent failures,
from failing with a critical section wait failure, to normal startup.

This bug may be related to bug #11488.
