2636 * The simplest solution to this - and many, many

2647 * have two completely different types of redraw (one
2648 * for full updates, which syncs the former with the

2650 * the latter with the former); yet another possibility
2651 * would be to have the Windows front end do what the
2652 * GTK one already does, and maintain a bitmap of the
2653 * current terminal appearance so that WM_PAINT becomes
2654 * completely trivial. However, this should do for now.
