There is no Metal backend in upstream Wine ;)

This may have been a mistake in commit
a5d2b3622b7b4f731075d9cd62c76c64c468666b; originally this only checked
It seems a little awkward to tie this to WINED3D_PIXEL_CENTER_INTEGER.
Would it make sense to instead detect the filling convention during
adapter initialisation, so that we can get rid of this for d3d9 and
before as well if possible? We could then just store the filling
convention offset in the wined3d_d3d_info structure.
