/**

 * 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__VTXFMT

 *   _mesa_install__vtxfmt

 *

 * When a feature defines dispatch entries, they are initialized by

 *   _mesa_init__dispatch

 *

 * When a feature has states, they are initialized and freed by

 *   _mesa_init_

 *   _mesa_free__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.
