| 1177 |  | Added support in normtiff for floating-point and 16-bit/sample TIFF input | 
| 1178 |  | files. | 
| 1256 |  | Made similar change for virtual sources to allow modifiers and aliases |

| 1262 |  | Made it so pcompos will read everything from a stream even if it doesn't |

| 1264 |  |  | 
| 1265 |  | Wrote ra_bmp program to convert to and from Windows BMP files (finally). |
