RGB 16 bits

first 10 lines returned by tiffinfo 16bitImage100dpi.tif gives:
TIFF Directory at offset 0x8 (8)
  Image Width: 138 Image Length: 338
  Resolution: 100, 100 pixels/inch
  Bits/Sample: 16
  Sample Format: unsigned integer
  Compression Scheme: None
  Photometric Interpretation: RGB color
  Orientation: row 0 top, col 0 lhs
  Samples/Pixel: 3
  Rows/Strip: 128

So I attached a zip containing 3 files with RGB 16 bits without compression (1
red, 1 green, 1 blue) => red one is ok, the 2 others are black.

The pb seems the 16 bits color case.

The mishandling seems to happen in the TIFF filter as the same image saved as
16 bit PNG displays normally, without any red cast.
