/**
* A feature can be anything. But most of them share certain characteristics.
*
* When a feature defines vtxfmt entries, they can be initialized and
* installed by
* _MESA_INIT_<FEATURE>_VTXFMT
* _mesa_install_<feature>_vtxfmt
*
* When a feature defines dispatch entries, they are initialized by
* _mesa_init_<feature>_dispatch
*
* When a feature has states, they are initialized and freed by
* _mesa_init_<feature>
* _mesa_free_<feature>_data
*
* Except for states, the others compile to no-op when a feature is disabled.
*
* The GLAPIENTRYs and helper functions defined by a feature should also
* compile to no-op when it is disabled. But to save typings and to catch
* bugs, some of them may be unavailable, or compile to ASSERT_NO_FEATURE()
* when the feature is disabled.
*
* A feature following the conventions may be used without knowing if it is
* enabled or not.
