   DESCRIPTION
       The RTBufferType structure defines slots to assign data buffers to
       using the [rtcSetGeometryBuffer], [rtcSetSharedGeometryBuffer], and
       [rtcSetNewGeometryBuffer] API calls.

       For most geometry types the RTC_BUFFER_TYPE_INDEX slot is used to
       assign an index buffer, while the RTC_BUFFER_TYPE_VERTEX is used to
       assign the corresponding vertex buffer.

       The RTC_BUFFER_TYPE_VERTEX_ATTRIBUTE slot can get used to assign
       arbitrary additional vertex data which can get interpolated using the
       [rtcInterpolate] API call.

       The RTC_BUFFER_TYPE_NORMAL, RTC_BUFFER_TYPE_TANGENT, and
       RTC_BUFFER_TYPE_NORMAL_DERIVATIVE are special buffers required to
       assign per vertex normals, tangents, and normal derivatives for some
       curve types.

       The RTC_BUFFER_TYPE_GRID buffer is used to assign the grid primitive
       buffer for grid geometries (see [RTC_GEOMETRY_TYPE_GRID]).

       The RTC_BUFFER_TYPE_FACE, RTC_BUFFER_TYPE_LEVEL,
       RTC_BUFFER_TYPE_EDGE_CREASE_INDEX, RTC_BUFFER_TYPE_EDGE_CREASE_WEIGHT,
       RTC_BUFFER_TYPE_VERTEX_CREASE_INDEX,
       RTC_BUFFER_TYPE_VERTEX_CREASE_WEIGHT, and RTC_BUFFER_TYPE_HOLE are
       special buffers required to create subdivision meshes (see
       [RTC_GEOMETRY_TYPE_SUBDIVISION]).

       The RTC_BUFFER_TYPE_TRANSFORM buffer is used to provide instance
       transformation information for instance array geometries (see
       [RTC_GEOMETRY_TYPE_INSTANCE_ARRAY]).

       The RTC_BUFFER_TYPE_FLAGS can get used to add additional flag per
       primitive of a geometry, and is currently only used for linear curves.
