2628 * when painting in WM_PAINT context we are restricted

2631 * rest of it was already visible, that remainder will

2633 * paint any character cell in a WM_PAINT context which
2634 * already has a pending update due to terminal output.
2635 * The simplest solution to this - and many, many
2636 * thanks to Hung-Te Lin for working all this out - is
2637 * not to do any actual painting at _all_ if there's a
2638 * pending terminal update: just mark the relevant
2639 * character cells as INVALID and wait for the
2640 * scheduled full update to sort it out.
2642 * I have a suspicion this isn't the _right_ solution.
2643 * An alternative approach would be to have terminal.c
2644 * separately track what _should_ be on the terminal
2645 * screen and what _is_ on the terminal screen, and
2646 * have two completely different types of redraw (one
2647 * for full updates, which syncs the former with the
2648 * terminal itself, and one for WM_PAINT which syncs
2649 * the latter with the former); yet another possibility
2650 * would be to have the Windows front end do what the
2651 * GTK one already does, and maintain a bitmap of the
2652 * current terminal appearance so that WM_PAINT becomes
2653 * completely trivial. However, this should do for now.
