2392 * We have to be careful about term_paint(). It will
2393 * set a bunch of character cells to INVALID and then
2394 * call do_paint(), which will redraw those cells and
2395 * _then mark them as done_. This may not be accurate:
2396 * when painting in WM_PAINT context we are restricted
2397 * to the rectangle which has just been exposed - so if
2398 * that only covers _part_ of a character cell and the
2399 * rest of it was already visible, that remainder will
2400 * not be redrawn at all. Accordingly, we must not
2401 * paint any character cell in a WM_PAINT context which
2402 * already has a pending update due to terminal output.
2403 * The simplest solution to this - and many, many
2404 * thanks to Hung-Te Lin for working all this out - is
2405 * not to do any actual painting at _all_ if there's a
2406 * pending terminal update: just mark the relevant
2407 * character cells as INVALID and wait for the
2408 * scheduled full update to sort it out.
2409 *
2410 * I have a suspicion this isn't the _right_ solution.
2411 * An alternative approach would be to have terminal.c
2412 * separately track what _should_ be on the terminal
2413 * screen and what _is_ on the terminal screen, and
2414 * have two completely different types of redraw (one
2415 * for full updates, which syncs the former with the
2416 * terminal itself, and one for WM_PAINT which syncs
2417 * the latter with the former); yet another possibility
2418 * would be to have the Windows front end do what the
2419 * GTK one already does, and maintain a bitmap of the
2420 * current terminal appearance so that WM_PAINT becomes
2421 * completely trivial. However, this should do for now.
