// Note 1: I found some comments at one point that noted that under OSX, using DSp AT ALL
// was worse than JUST using the AGL_FULLSCREEN system. Right now, code uses a combo
// of the two under OSX, so we'll want to performance-test the two options...
// Note 2: Card Profiling code isn't doing anything.
// Note 3: Screen-res list building is hardcoded, and should tap DSp.
// Note 4: Gamma support.
// flip this if we want smooth gamma-fades when switching screenres or in/out of DSp.
// generally, it's less nice but easier to find probs if we just leave it off, even for release.
