// plTransitionMgr - Class to handle fullscreen transitions (fades, etc) //
// //
// Note: eventually, I would like to drive these transitions on material //
// animations (it's just a big screen-covering plate with a material, //
// after all). This would allow the artists to specify their own //
// transitions and do really cool effects. However, that would require //
// somehow loading the materials in, and I'm not sure exactly how to do //
// that.... //
