Issue 1925
{{{
Author: ami_stuff Date: 2010-05-08.17:03:35
Attached TIFF file decodes incorrectly, maybe because FFmpeg thinks it is
<=8bit
image, while it is really 24bit.
IrfanView can decode it correctly.

Works fine with ImageMagick.

This TIFF uses (8 bits per sample) x (3 samples per pixel) scheme and
SamplesPerPixel entry is ignored now. I'll try to support it.

This patch should fix it but I cannot test if it does not break decoding
other TIFF files now so I shan't apply it.
