2624 * _then mark them as done_. This may not be accurate:
2625 * when painting in WM_PAINT context we are restricted

2627 * that only covers _part_ of a character cell and the
2628 * rest of it was already visible, that remainder will
2629 * not be redrawn at all. Accordingly, we must not
2630 * paint any character cell in a WM_PAINT context which
2631 * already has a pending update due to terminal output.
2632 * The simplest solution to this - and many, many
2633 * thanks to Hung-Te Lin for working all this out - is
2634 * not to do any actual painting at _all_ if there's a
2635 * pending terminal update: just mark the relevant
2636 * character cells as INVALID and wait for the
2637 * scheduled full update to sort it out.
2639 * I have a suspicion this isn't the _right_ solution.
2640 * An alternative approach would be to have terminal.c
2641 * separately track what _should_ be on the terminal
2642 * screen and what _is_ on the terminal screen, and
2643 * have two completely different types of redraw (one
2644 * for full updates, which syncs the former with the
2645 * terminal itself, and one for WM_PAINT which syncs
2646 * the latter with the former); yet another possibility
2647 * would be to have the Windows front end do what the
2648 * GTK one already does, and maintain a bitmap of the
2649 * current terminal appearance so that WM_PAINT becomes
2650 * completely trivial. However, this should do for now.
