Backends: DirectX9: explicitely setting up more graphics states to increase compatibility with unusual non-default states. (#4063)
Added D3DRS_FILLMODE, D3DRS_ZWRITEENABLE, D3DRS_RANGEFOGENABLE, D3DRS_SPECULARENABLE, D3DRS_STENCILENABLE, D3DRS_CLIPPING. Reordered some to match order in DX9 headers.
