[DDraw] Fix AoE2 font rendering (in most cases)

No idea actually for Warblade but at least for AoE2 it fixes the fonts in
the game itself. The fonts in the menu are still black (and from my tests in
QEMU they should be white instead).

Will attach the patch to the bug report and wait for answers....
