Subject: [PATCH] From Ralf Kern, "the attached color mapped TIFF file
 klink1_l.tif is incorrectly read as GL_LUMINANCE data instead of GL_RGB data.
 You can easily check with "osgViewer --image klink1_l.tif".

The bug is in ReaderWriterTIFF.cpp function simage_tiff_load, where
numComponents_ret is incorrectly set to 1 instead of 3 for color mapped
data."
