Correction: TIFF is one of the very few formats (the other is HDF) for
            which ImageMagick does not provide native BLOB support.

The reason for lack of support is because the libtiff API is not
adequate.  To be adequate, the API would need to support working with
striped, or tiled data (using a accessor function we provide), and not
require a file descriptor. Since TIFF is a very important format, we
would really like to support TIFF BLOBs in ImageMagick.
