2490 * not be redrawn at all. Accordingly, we must not
2491 * paint any character cell in a WM_PAINT context which
2492 * already has a pending update due to terminal output.
2493 * The simplest solution to this - and many, many
2494 * thanks to Hung-Te Lin for working all this out - is
2495 * not to do any actual painting at _all_ if there's a
2496 * pending terminal update: just mark the relevant
2497 * character cells as INVALID and wait for the
2498 * scheduled full update to sort it out.
2499 *
2500 * I have a suspicion this isn't the _right_ solution.
2501 * An alternative approach would be to have terminal.c
2502 * separately track what _should_ be on the terminal
2503 * screen and what _is_ on the terminal screen, and
2504 * have two completely different types of redraw (one
2505 * for full updates, which syncs the former with the
2506 * terminal itself, and one for WM_PAINT which syncs
2507 * the latter with the former); yet another possibility
2508 * would be to have the Windows front end do what the
2509 * GTK one already does, and maintain a bitmap of the
2510 * current terminal appearance so that WM_PAINT becomes
2511 * completely trivial. However, this should do for now.
