/**

* Constant State Object (CSO) cache.
- *
+ *
* The basic idea is that the states are created via the
* create_state/bind_state/delete_state semantics. The driver is expected to
* perform as much of the Gallium state translation to whatever its internal
* mechanism where it stores the created states. When the pipeline needs an
* actual state change, a bind call is issued. In the bind call the driver
* gets its already translated representation.
- *
+ *
* Those semantics mean that the driver doesn't do the repeated translations
* of states on every frame, but only once, when a new state is actually
* created.
- *
+ *
* Even on hardware that doesn't do any kind of state cache, it makes the
* driver look a lot neater, plus it avoids all the redundant state
* translations on every frame.
- *
+ *
* Currently our constant state objects are:
* - alpha test
* - blend
* - rasterizer (old setup)
* - sampler
* - vertex shader
- *
+ * - vertex elements
+ *
* Things that are not constant state objects include:
* - blend_color
* - clip_state
* - scissor_state
* - texture_state
* - viewport_state
