This was needed unconditionally in the past to apply fog, but since we're
using the ARBfp fog defines it is only needed if an sRGB correction is done
at the end of the shader.

msvfw32: Clearly separate the 16-bit code out of the rest by wrapping 16-bit message functions in thunks.

fusion: CompareAssemblyIdentity() and GetAssemblyIdentityFromFile() are unused stubs and don't belong in fusion.dll. So remove them.

inetmib1: Make sure the successor to an item doesn't have an identical key as it, to prevent infinite loops in table enumeration.

wininet: Add a read-ahead buffer to allow InternetQueryDataAvailable to return the right values in chunked mode.

I just copied them from Wine's 16 pixel MS Sans Serif font.

Besides the cleanup this patch will help to implement D3DSPDM_PARTIALPRECISION 
with GL_NV_vertex_program2_option / GL_NV_fragment_program_option.
