Stefan Dösinger 98faed8ff5 wined3d: Start the state splitup. 
The idea of this patchset is to split the monolithic state set into 3
parts, vertex processing, fragment processing and other states(depth,
stencil, scissor, ...). The states will be provided in templates which
can be (mostly) independently combined, and are merged into a single
state table at device creation time. This way we retain the advantages
of the single state table and having the advantage of separated
pipeline implementations which can be combined without any manually
written glue code.
