2526 * when painting in WM_PAINT context we are restricted
2527 * to the rectangle which has just been exposed - so if
2528 * that only covers _part_ of a character cell and the
2529 * rest of it was already visible, that remainder will
2530 * not be redrawn at all. Accordingly, we must not
2531 * paint any character cell in a WM_PAINT context which
2532 * already has a pending update due to terminal output.
2533 * The simplest solution to this - and many, many
2534 * thanks to Hung-Te Lin for working all this out - is
2535 * not to do any actual painting at _all_ if there's a
2536 * pending terminal update: just mark the relevant
2537 * character cells as INVALID and wait for the
2538 * scheduled full update to sort it out.
2540 * I have a suspicion this isn't the _right_ solution.
2541 * An alternative approach would be to have terminal.c
2542 * separately track what _should_ be on the terminal
2543 * screen and what _is_ on the terminal screen, and
2544 * have two completely different types of redraw (one
2545 * for full updates, which syncs the former with the
2546 * terminal itself, and one for WM_PAINT which syncs
2547 * the latter with the former); yet another possibility
2548 * would be to have the Windows front end do what the
2549 * GTK one already does, and maintain a bitmap of the
2550 * current terminal appearance so that WM_PAINT becomes
2551 * completely trivial. However, this should do for now.
