2607 * _then mark them as done_. This may not be accurate:
2608 * when painting in WM_PAINT context we are restricted
2609 * to the rectangle which has just been exposed - so if
2610 * that only covers _part_ of a character cell and the
2611 * rest of it was already visible, that remainder will
2612 * not be redrawn at all. Accordingly, we must not
2613 * paint any character cell in a WM_PAINT context which
2614 * already has a pending update due to terminal output.
2615 * The simplest solution to this - and many, many
2616 * thanks to Hung-Te Lin for working all this out - is
2617 * not to do any actual painting at _all_ if there's a
2618 * pending terminal update: just mark the relevant
2619 * character cells as INVALID and wait for the
2620 * scheduled full update to sort it out.
2622 * I have a suspicion this isn't the _right_ solution.
2623 * An alternative approach would be to have terminal.c
2624 * separately track what _should_ be on the terminal
2625 * screen and what _is_ on the terminal screen, and
2626 * have two completely different types of redraw (one
2627 * for full updates, which syncs the former with the
2628 * terminal itself, and one for WM_PAINT which syncs
2629 * the latter with the former); yet another possibility
2630 * would be to have the Windows front end do what the
2631 * GTK one already does, and maintain a bitmap of the
2632 * current terminal appearance so that WM_PAINT becomes
2633 * completely trivial. However, this should do for now.
