2531 * We have to be careful about term_paint(). It will
2532 * set a bunch of character cells to INVALID and then
2533 * call do_paint(), which will redraw those cells and
2534 * _then mark them as done_. This may not be accurate:
2535 * when painting in WM_PAINT context we are restricted
2536 * to the rectangle which has just been exposed - so if
2537 * that only covers _part_ of a character cell and the
2538 * rest of it was already visible, that remainder will
2539 * not be redrawn at all. Accordingly, we must not
2540 * paint any character cell in a WM_PAINT context which
2541 * already has a pending update due to terminal output.
2542 * The simplest solution to this - and many, many
2543 * thanks to Hung-Te Lin for working all this out - is
2544 * not to do any actual painting at _all_ if there's a
2545 * pending terminal update: just mark the relevant
2546 * character cells as INVALID and wait for the
2547 * scheduled full update to sort it out.
2549 * I have a suspicion this isn't the _right_ solution.
2550 * An alternative approach would be to have terminal.c
2551 * separately track what _should_ be on the terminal
2552 * screen and what _is_ on the terminal screen, and
2553 * have two completely different types of redraw (one
2554 * for full updates, which syncs the former with the
2555 * terminal itself, and one for WM_PAINT which syncs
2556 * the latter with the former); yet another possibility
2557 * would be to have the Windows front end do what the
2558 * GTK one already does, and maintain a bitmap of the
2559 * current terminal appearance so that WM_PAINT becomes
2560 * completely trivial. However, this should do for now.
