Final patch

This patch fixes the issues that we are seeing with the JPEG2000 images in the
FTS files EXCEPT for the issues related to SmaskInData.  Those images will be
addressed by a different patch.  

With this patch, support is also in place for faster 16 bit image rendering due
to the improved ICC support, which lets us avoid the multiple conversions from
16 bit to frac to float to unsigned short to byte which occurred in the old
flow.  Also, the jasper interface will now, when it encounters a 16 bit or 12
bit image, use the higher bit depth renderer and pass the data along. 
Previously, we were truncating to 8bits in our jasper interface.  This patch
has been regression tested and checked with bmpcmp.
