+ * A feature can be anything. But most of them share certain characteristics.
+ *
+ * When a feature defines driver entries, they can be initialized by
+ * _MESA_INIT_<FEATURE>_FUNCTIONS
+ *
+ * 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.
