scenejs setIndices setPrimitive

a.js

    SceneJS.Geometry.prototype.setIndices = function (data) {
        if (data.indices && this._core.indexBuf) {
            this._boundary = null;
            var core = this._core;
            core.indexBuf.bind();
            core.indexBuf.setData(new Uint16Array(data.indices), data.indicesOffset || 0 );
            core.arrays.indices.set(data.indices, data.indicesOffset || 0 );
            this._engine.display.imageDirty = true;
        }
    };    
 
    SceneJS.Geometry.prototype.setPrimitive = function (data) {
      this._core.primitive = this._getPrimitiveType(data.primitive);
      this._engine.display.imageDirty = true;
    }

Nice - I'll include that in the next SceneJS iteration - thanks!
