Camparison needs to take place with a bytestring.

Strange, I created that patch from the Google online editor.

The problem is that dds.py compares string values to byte values at several 
points, which always fails because '' and b'' are not the same.

Theres more than a simple glitched comparison but nothing esoteric. 

I created a pyglet clone at
hg clone https://ccanepacc@code.google.com/r/ccanepacc-fixups/
to fix different issues with pyglet/image/codecs/dds.py

The last four commits deals with this issue, and each commit log comments the 
details.

The second commit (r35262e3ee397) includes a local variable renaming thats 
completed in the last commit (r613cc5b71b6e), sorry for the slip.

I started by running the pyglet test DDS_RGB_DXT1_LOAD.py under py3 and fixing 
the problems as they appear, then tested all the DDS_*; they look fine now.

The final commit was also tested with py 2.6.6 , rendering is the same as in 
3.2.1

just for convenience a single patch with all the changes

To recap
    fixed bytes vs str issues, a failing unpacking when the dds variant was unknown, a type mismatch due to division changes in py2 - py3

Now tests/image/DDS_* tests are working in both pythons, with same rendering.
