  >raw + exif formats:
 
-   > rethink raw format header parser, apparently canon and nikon both use the TIFF file format,
-     so it is possible that the same magic header can be in both formats - it only works now
-     because Canon header list ignores Motorola alignment, which is what Nikon uses. Additionally
-     matching CRW format uses a magic "HEADCCDR" offset 6 bytes into the file, first two bytes are
-     similar to tiff for specifying byte alignment (II or MM), so the current code will also pick
-     up tiff files. Whatever happens here, we want to avoid mmap'ing the file until we are sure.

+   > all thats left to do is possibly mmap the file so we have all the tiff data available when
+     looking for the make TIFF tag (0x10f) as it may not always fit within data available from
+     the first read() in image-load.c.

      parsers that involve tiff.
