2620 * have two completely different types of redraw (one
2621 * for full updates, which syncs the former with the

2623 * the latter with the former); yet another possibility
2624 * would be to have the Windows front end do what the
2625 * GTK one already does, and maintain a bitmap of the
2626 * current terminal appearance so that WM_PAINT becomes
2627 * completely trivial. However, this should do for now.
