43 * A feature can be anything. But most of them share certain characteristics.
44 *
45 * When a feature defines vtxfmt entries, they can be initialized and
46 * installed by
47 * _MESA_INIT_<FEATURE>_VTXFMT
48 * _mesa_install_<feature>_vtxfmt
49 *
50 * When a feature defines dispatch entries, they are initialized by
51 * _mesa_init_<feature>_dispatch
52 *
53 * When a feature has states, they are initialized and freed by
54 * _mesa_init_<feature>
55 * _mesa_free_<feature>_data
56 *
57 * Except for states, the others compile to no-op when a feature is disabled.
58 *
59 * The GLAPIENTRYs and helper functions defined by a feature should also
60 * compile to no-op when it is disabled. But to save typings and to catch
61 * bugs, some of them may be unavailable, or compile to ASSERT_NO_FEATURE()
62 * when the feature is disabled.
63 *
64 * A feature following the conventions may be used without knowing if it is
65 * enabled or not.
