2671 * when painting in WM_PAINT context we are restricted

2676 * paint any character cell in a WM_PAINT context which
2677 * already has a pending update due to terminal output.
2678 * The simplest solution to this - and many, many
2679 * thanks to Hung-Te Lin for working all this out - is
2680 * not to do any actual painting at _all_ if there's a

2686 * An alternative approach would be to have terminal.c
2687 * separately track what _should_ be on the terminal
2688 * screen and what _is_ on the terminal screen, and
2689 * have two completely different types of redraw (one
2690 * for full updates, which syncs the former with the
2691 * terminal itself, and one for WM_PAINT which syncs
2692 * the latter with the former); yet another possibility
2693 * would be to have the Windows front end do what the
2694 * GTK one already does, and maintain a bitmap of the
2695 * current terminal appearance so that WM_PAINT becomes
2696 * completely trivial. However, this should do for now.
