Mutes the logging:
fixme:(dll/directx/wine/ddraw/utils.c:584) Unhandled flags 0x20.
gets logged many times per second.
It does affect several applications, e.g. the game 'Anno 1602' from 1998, and the 'Diablo 2 demo' from rapps,
For both games it can be observed with both: our VBEMP driver and the VBox4.3.12 3D-accelerated-driver.
Muting may improve performance a bit in such apps.
It gets logged although no missing features can be perceived visually in the rendering.
Fix it by importing Wine-commit b943c7910b3261c9603343369cd632f7a3b56bba
