KGC was used *not* because it resembled QCanvas (it does not IIRC), but because QGV could not perform fast enough for some games. Their survival in KDE 4 and conversion to KDE 4 depended on getting something faster. I have heard QGV is faster now. I believe our early work on it with KDE Games helped make that happen. I do *not* know if QGV would now be fast enough, nor am I about to re-program the graphics of my own game (for the fifth time) to find that out. KGC is a lightweight library based on painting QPixmaps. Compared to that earlier crisis, the problem with Oxygen window dragging was a ripple versus a tsunami. So please can we stop this thread now?
