2625 * The simplest solution to this - and many, many

2636 * have two completely different types of redraw (one
2637 * for full updates, which syncs the former with the

2639 * the latter with the former); yet another possibility
2640 * would be to have the Windows front end do what the
2641 * GTK one already does, and maintain a bitmap of the
2642 * current terminal appearance so that WM_PAINT becomes
2643 * completely trivial. However, this should do for now.
