ogl_tex: bind() implementation much simplified; also fix bug that set TMU correctly when disabling texturing wsdl: fix stdout.txt redirect; now works regardless of current directory. also no longer disable file buffering except when in full debug mode (because it's so slow). also add minimize button to caption bar in windowed mode. This was SVN commit r2919.
