[Mesa-dev] [PATCH 14/75] st/nine: Initial mixed vertex processing support

[Axel Davy]

In mixed vertex processing, the user can enable or disable
software vertex processing. It is on hardware by default.

This feature is not a state, and thus the setting doesn't
need to be recorded by stateblocks.
