GLES SW: inline with HW using 0,0,1 for non-normal case

This is HW equivalent

					case GE_PROJMAP_NORMALIZED_NORMAL:  // Use normalized transformed normal as source
						if (hasNormal)
							temp_tc = "vec4(normalize(a_normal), 1.0)";
						else
							temp_tc = "vec4(0.0, 0.0, 1.0, 1.0)";
						break;
					case GE_PROJMAP_NORMAL:  // Use non-normalized transformed normal as source
						if (hasNormal)
							temp_tc = "vec4(a_normal, 1.0)";
						else
							temp_tc = "vec4(0.0, 0.0, 1.0, 1.0)";
						break;
					}
