[Gtkradiant] 64-bit issues

[Branan Riley]

I've already sent my patch for the 64-bit issues with the DDS loader,
and that seems to work perfectly now. I'm planning on looking into the
issue with drawing entity boxes in the 2D views[1]. Are there any
other issues that people have run into with GtkRadiant that should be
addressed?

Also,are there any plans to release any 1.5.X bugfix releases, or
would my efforts be better but towards playing with ZeroRadiant?
