+		of UInt16Array, and [page:Boolean normalized] is true, the values 0 - +65535 in the array
+		 data will be mapped to 0.0f - +1.0f in the GLSL attribute. An Int16Array (signed) would map
+		 from -32767 - +32767  to -1.0f - +1.0f. If [page:Boolean normalized] is false, the values
+		 will be converted to floats unmodified, i.e. 32767 becomes 32767.0f.
