2675 * when painting in WM_PAINT context we are restricted

2678 * rest of it was already visible, that remainder will

2680 * paint any character cell in a WM_PAINT context which
2681 * already has a pending update due to terminal output.
2682 * The simplest solution to this - and many, many
2683 * thanks to Hung-Te Lin for working all this out - is
2684 * not to do any actual painting at _all_ if there's a
2685 * pending terminal update: just mark the relevant
2686 * character cells as INVALID and wait for the
2687 * scheduled full update to sort it out.
2689 * I have a suspicion this isn't the _right_ solution.
2690 * An alternative approach would be to have terminal.c
2691 * separately track what _should_ be on the terminal
2692 * screen and what _is_ on the terminal screen, and
2693 * have two completely different types of redraw (one
2694 * for full updates, which syncs the former with the
2695 * terminal itself, and one for WM_PAINT which syncs
2696 * the latter with the former); yet another possibility
2697 * would be to have the Windows front end do what the
2698 * GTK one already does, and maintain a bitmap of the
2699 * current terminal appearance so that WM_PAINT becomes
2700 * completely trivial. However, this should do for now.
