2628 * _then mark them as done_. This may not be accurate:
2629 * when painting in WM_PAINT context we are restricted
2630 * to the rectangle which has just been exposed - so if
2631 * that only covers _part_ of a character cell and the
2632 * rest of it was already visible, that remainder will
2633 * not be redrawn at all. Accordingly, we must not
2634 * paint any character cell in a WM_PAINT context which
2635 * already has a pending update due to terminal output.
2636 * The simplest solution to this - and many, many
2637 * thanks to Hung-Te Lin for working all this out - is
2638 * not to do any actual painting at _all_ if there's a
2639 * pending terminal update: just mark the relevant
2640 * character cells as INVALID and wait for the
2641 * scheduled full update to sort it out.
2643 * I have a suspicion this isn't the _right_ solution.
2644 * An alternative approach would be to have terminal.c
2645 * separately track what _should_ be on the terminal
2646 * screen and what _is_ on the terminal screen, and
2647 * have two completely different types of redraw (one
2648 * for full updates, which syncs the former with the
2649 * terminal itself, and one for WM_PAINT which syncs
2650 * the latter with the former); yet another possibility
2651 * would be to have the Windows front end do what the
2652 * GTK one already does, and maintain a bitmap of the
2653 * current terminal appearance so that WM_PAINT becomes
2654 * completely trivial. However, this should do for now.
