Detailed Description
This class provides map rendering functionality for vector tile layers. In render() function (assumed to be run in a worker thread) it will:
fetch vector tiles using QgsVectorTileLoader
decode raw tiles into QgsFeature objects using QgsVectorTileDecoder
render tiles using a class derived from QgsVectorTileRenderer
