libsquish is C++, so it's not going to be of much use.  I like the
idea of having it in lib, it will solve the issue of distro's not having
that package available any more. (Debian, Arch).

Current we have three patchset in staging for DXTn support.
https://github.com/wine-staging/wine-staging/tree/master/patches/wined3d-DXTn
https://github.com/wine-staging/wine-staging/tree/master/patches/d3dx9_36-DXTn
https://github.com/wine-staging/wine-staging/tree/master/patches/d3dx9_36-Texture_Align

These rely on loading libtxc_dxtn dynamically, so if we start by
getting your patch to store it in lib.  Then we can update the other patches
to reflect this direction.

Alistair.
