[Gtkradiant] Bug with libs/ddslib/ddslib.c lines 693 to 723 on 64 bit systems.

[Branan Riley]

Has anyone figured this out yet? I glanced over the code that
determines width and height, and it looks OK to me.

When the DDS data is loaded, how is it done? is it a chunk of memory
that's cast to a ddsBuffer_t*? if so, the problem might be alignment
issues caused by "void* surface" on line 184 of ddslib.h. Other than
that, my cursory glance reveals nothing of use.
