Note that minMipLookup and magLookup aren't particularly safe to use,
they're global arrays initialized from IWineD3DImpl_FillGLCaps(). The same
goes for the other global dynamic lookup tables.

lpData is already a pointer to BYTE. Note that the cast for the normal
data was actually wrong.

It uses some functions that are inlined in i386, but are explicitly
linked on other architectures, which means that qmgrprxy should link
to ntdll.
