2422 * We have to be careful about term_paint(). It will

2425 * _then mark them as done_. This may not be accurate:
2426 * when painting in WM_PAINT context we are restricted
2427 * to the rectangle which has just been exposed - so if
2428 * that only covers _part_ of a character cell and the
2429 * rest of it was already visible, that remainder will
2430 * not be redrawn at all. Accordingly, we must not
2431 * paint any character cell in a WM_PAINT context which
2432 * already has a pending update due to terminal output.
2433 * The simplest solution to this - and many, many
2434 * thanks to Hung-Te Lin for working all this out - is
2435 * not to do any actual painting at _all_ if there's a
2436 * pending terminal update: just mark the relevant
2437 * character cells as INVALID and wait for the
2438 * scheduled full update to sort it out.
2440 * I have a suspicion this isn't the _right_ solution.
2441 * An alternative approach would be to have terminal.c
2442 * separately track what _should_ be on the terminal
2443 * screen and what _is_ on the terminal screen, and
2444 * have two completely different types of redraw (one
2445 * for full updates, which syncs the former with the
2446 * terminal itself, and one for WM_PAINT which syncs
2447 * the latter with the former); yet another possibility
2448 * would be to have the Windows front end do what the
2449 * GTK one already does, and maintain a bitmap of the
2450 * current terminal appearance so that WM_PAINT becomes
2451 * completely trivial. However, this should do for now.
