Added "Hacks" tab to OGL plugin config window and the hack option "Invert Depth". Use hacks to figure out some graphics bugs like the logo in ZWW is not a glDepth problem as I would figured it was. These hacks should be temp until the problem has been solved correctly. Also more hacks can help us figure out graphics problems we do not understand faster.
