library hangs when reading linear images

[GoogleCodeExporter]

What steps will reproduce the problem?
Load any non-compressed (DDPF_RGB) DDS image that has a zero alpha mask
(for example with the nvdecompress utility)

What is the expected output? What do you see instead?
Load hangs infinitely.

What version of the product are you using? On what operating system?
Latest svn (revision 94).

Please provide any additional information below.
A patch which fixes the problem is attached. Note that I was not entirely
sure how to fix the convert function, but it seems to work.

I figured out what the code in the convert function was supposed to do. :-) 
Attached
is an improved patch. Please ignore the one I posted before.

Thanks for reporting and fixing the problem! The pixel format conversion code 
was 
not heavily tested, and I'm not surprised there were errors. I've committed 
your 
patch and done some cleanups. In particular I've moved the pixel format 
conversion 
helpers to PixelFormat.h, since they were duplicated in two different places.
