2560 * paint any character cell in a WM_PAINT context which
2561 * already has a pending update due to terminal output.
2562 * The simplest solution to this - and many, many
2563 * thanks to Hung-Te Lin for working all this out - is
2564 * not to do any actual painting at _all_ if there's a

2570 * An alternative approach would be to have terminal.c

2573 * have two completely different types of redraw (one
2574 * for full updates, which syncs the former with the
2575 * terminal itself, and one for WM_PAINT which syncs
2576 * the latter with the former); yet another possibility
2577 * would be to have the Windows front end do what the
2578 * GTK one already does, and maintain a bitmap of the
2579 * current terminal appearance so that WM_PAINT becomes
2580 * completely trivial. However, this should do for now.
