| * 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. |
