If restore does not work, device must be recreated. IIRC

For my own future reference:
The program was crashing on the DrawPrimitiveUP call in
d3d_flush_vertex_cache. Upgrading the nvidia drivers seemed to make
the crashes go away.
The remaining problem is that after alt-tabbing out, the program often
will not restore. The device Reset calls return D3DERR_INVALIDCALL.
