This was tested with Sacred Gold from GOG.com. I tried the original demo but it
doesn't have the bug: the demo runs in 16-bit color mode whereas the problem
occurs only in 32-bit color mode.
I reproduced the problem with Nvidia binary drivers 381.22 and with
nouveau/mesa 17.1.4, too.

The problem: in-game characters are invisible.

wined3d: Use the blitter interface in wined3d_cs_exec_clear().

Characters are visible with the previous commit.
In the game configuration tool if I uncheck the 32 bit Color Depth option, the
problem doesn't occur.
