…TA for Byte/UInt16/Int16 data types Add a specialization when a VRTComplexSource has only a <NODATA> value and no other processing (scaling, color table expansion, LUT), and that the source data type is Byte, UInt16, Int16 On a 3-band 20791x22938 Byte VRT, "gdal_translate in.vrt out.tif" goes from 9.8s to 4s
