- * A GrGeomteryProcessor is used to perform computation in the vertex shader and
- * add support for custom vertex attributes. A GrGemeotryProcessor is typically
- * tied to the code that does a specific type of high-level primitive rendering
- * (e.g. anti-aliased circle rendering). The GrGeometryProcessor used for a draw is
- * specified using GrDrawState. There can only be one geometry processor active for
- * a draw. The custom vertex attributes required by the geometry processor must be
- * added to the vertex attribute array specified on the GrDrawState.
- * GrGeometryProcessor subclasses should be immutable after construction.
