Anisotropy and texture filters are orthogonal in GL. In D3D
D3DTEXF_ANISOTROPIC just selects the best (linear) filter type and enables
anisotropy.

This is already initialized to an appropriate value in basetexture_init().
Also fix the indentation while we're at it.

Also makes the code only load the libgsm library only when it is used
instead of on initialization of the dll.

widl: Store the pointer description in the type rather than base type so that it gets re-written when the type is re-written.

The iTunes 8 installer database has an integer column of size 1 which
takes up two bytes at storage level, so adjust the column size calculation
to account for this difference.

Also add some comments.

These don't have a whole lot to do with each other.

It's a bit pointless to keep printing FIXMEs after the first time.
